Abstract
A circuit module equipped with a primary coil of a step-down transformer formed by primary coils of a plurality of transformer elements connected in series with each other and a secondary coil formed by secondary coils of the transformer elements connected in series with each other, includes a printed substrate on which the transformer elements are mounted in a lengthwise direction, a connection terminal coupled to a first end of the primary coil of the step-down transformer and connection terminals coupled to the secondary coil of the step-down transformer, the connection terminals are positioned such that the transformer elements are interposed therebetween. As a result, provided are a transformer module that reduces the effect of a high-voltage portion on a low-voltage portion by securing a distance between the high-voltage portion and the low-voltage portion, and a power reception device and a power transmission device equipped with the transformer module.
