TRANSFORMER MODULE AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To enable high density mounting even if a transformer is constituted of a substrate which is difficult to self-stand in a transformer module including a transformer constituted of a plurality of coils, and to improve heat dissipation by surface-mounting the transformer module on a mounting substrate while controlling cost.

SOLUTION: The transformer module 2 includes a pair of substrates 10 and 20 arranged at intervals in the thickness direction where one coil 30 constituting a transformer 50 is constituted by winding a wire 32 around a bobbin 31 and fixed between the pair of substrates 10 and 20, and other coils 15 and 25 are constituted of wiring patterns formed on the substrates 10 and 20, respectively.
