Coil-embedded dust core and method for manufacturing the same, and coil and method for manufacturing the same
First Claim
1. A coil-embedded dust core comprising:
- a coil including a winding section, in which a flat conductor having front and back surfaces opposed to each other with a predetermined distance, is wound;
a first end section which is formed by said conductor and is extended from said winding section;
a second end section which is formed by said conductor and is extended from said winding section at a position different from said first end section, with said winding section being insulation coated; and
a green body which is formed of insulation-coated ferromagnetic metal particles and in which said coil is embedded, wherein either one of said front and back surfaces of said first end section and either one of said front and back surfaces of said second end section are formed so as to be on the same plane.

Abstract
There are provided a coil-embedded dust core that provides high inductance and a method for manufacturing the same. The coil-embedded dust core includes a coil 1 formed by winding a flat conductor 2 and a green body 10 comprising of ferromagnetic metal powder coated with an insulating material. The coil 1 is composed of a winding section 3 in which the flat conductor 2 having front and back surfaces opposed to each other with a predetermined distance is wound and lead-out end sections 4a and 4b that are extended from the winding section 3. Either one of the front and back surfaces of the lead-out end section 4a and either one of the front and back surfaces of the lead-out end section 4b are formed so as to be on the same plane. By using the coil 1 in which the both end sections (lead-out end sections 4a and 4b) are formed on the same plane, the coil-embedded dust core can be made smaller in size, and high inductance can be provided.
