PROBLEM TO BE SOLVED: To provide a compact power supply easy to use a common semiconductor component.SOLUTION: The power supply includes: a transformer 2, a primary semiconductor component 3a, a secondary semiconductor component 3b, a choke coil 4, a case 5, a control circuit board 7 and a lead wire part 6. The control circuit board 7 is connected to at least the primary semiconductor component 3a of two semiconductor components 3. The lead wire part 6 configures a signal transmission path between the semiconductor component 3 and the control circuit board 7. The lead wire part 6 is configured to be a different component from the semiconductor component 3. The lead wire part 6 is sealed on a wall part 51 of the case 5. The lead wire part 6 is connected to an electrode 32 formed on the semiconductor components 3a, 3b. |
