First Claim
Patent Images
1. A thin transformer comprising:
- an insulating paper having one of a pressure sensitive adhesive and an adhesive disposed on both faces thereof;
a multilayered coil configured by having said insulating paper inserted into at least one place between thin coil layers; and
magnetic cores mounted to said multilayered coil from above and below.

Abstract
A multilayered coil is formed by inserting insulating paper 13 having either a pressure sensitive adhesive or an adhesive disposed on both faces thereof into at least one place between thin coil layers and then magnetic cores 15 are mounted to the multilayered coil from above and below. Thus, a thin transformer for a switching power supply is provided, in which variation in distance between coil 11 and coil 12, of which one is disposed over the other, variation in distance of coil 11 and coil 12 from magnetic core 15 and the like are suppressed.
