PROBLEM TO BE SOLVED: To provide a printed coil transformer which secures insulation properties between a first printed coil board and a second printed coil board, and which is capable of securing stabilization of power supply characteristics and heat dissipation using a resin having excellent thermal conductivity.SOLUTION: Resin receiving parts 16 are provided to through-holes 15 of printed coil boards 13A, 13B, 14A, 14B, and resin for entering between a pair of magnetic substance cores 11A, 11B and projecting therefrom enters into these resin receiving parts, thereby capable of preventing the resin from interposing in a gap of a fitting part between the pair of magnetic substance cores. As a result, stabilization of power supply characteristics can be secured, and insulation properties intended by engineering and heat dissipation effect can also be secured, thereby being connected to simplification of a manufacturing step. |
