Document Type and Number:
WIPO Patent Application WO/2007/132878
Kind Code:
A1
Abstract:
It is possible to provide a transformer core which can be mounted on a coil having
both ends connected to a substrate or the like and can simplify the step for arranging
an adhesive layer and suppress fluctuation of a magnetic gap. The transformer
core (1) includes: a rectangular spacer (5, 20) having a region where a first convex
portion (10, 21) is formed on the four sides of one of the surfaces as a unitary block
and the first convex portion is not provided at least at a part of a pair of two opposing
sides; and a sheet-shaped adhesive layer (6) bonded to a region where at least
the first convex portion is not provided on the one of the surfaces of the spacer
