Abstract

An adhesive member is disclosed. The adhesive member includes a first release element, a second release element and a body. The body includes a first adhesive surface and a second adhesive surface. The body also includes a first end face and a second end face. The first end face forms an acute angle with the first release element located on the body. The second end face faces the first end face and forms an obtuse angle with the second release element of the body.

Claims

1. An adhesive member comprising:

a first release element;

a second release element, wherein said second release element is made of identical material as said first release element; and

an adhesive body having a first adhesive surface and a second adhesive surface, wherein said first release element is removably attached to sad first adhesive surface, and said second release element is removably attached to said second adhesive surface, wherein sad adhesive body includes

a first end face forming an acute angle with said first release element and an obtuse angle with said second release element; and

a second end face forming an obtuse angle with said first release element and an acute angle with said second release element

in order to allow easy removal of said first and second release elements from said adhesive body, wherein said first and second release elements are to be discarded after removal from said adhesive body.

2. The adhesive member of claim 1, wherein said first and second release elements are made of resinous film.

3. The adhesive member of claim 1, wherein said first and second release elements are made of paper.

4. The adhesive member of claim 1, wherein said adhesive body is made of thermal rubber for heat dissipation.

5. The adhesive member of claim 4, wherein said adhesive body is made of a conductive silicon resin.

6. The adhesive member of claim 1, wherein the forces for removing said first and second release elements from said adhesive body are substantially identical.

7. The adhesive member of claim 1, wherein said first and second release elements are made of one type of material.

8. An electronic device comprising:

a first chassis having a keyboard; and

a second chassis connected to said first chassis, wherein said second chassis includes a display and an antenna;

an adhesive body includes a first adhesive surface attached to said antenna and a second adhesive surface attached to said second chassis, wherein said adhesive body includes

a first end face forming an acute angle with said antenna and an obtuse angle with said second chassis; and

a second end face forming an obtuse angle with said antenna and an acute angle with said second chassis.

9. The electronic device of claim 8, wherein said adhesive body is made of thermal rubber for heat dissipation.

10. The electronic device of claim 9, wherein said adhesive body is made of a conductive silicon resin.
