PROBLEM TO BE SOLVED: To provide a power supply unit in which an insulating board and an upright portion can be aligned at a low cost.SOLUTION: A power supply unit includes an insulating board 2 composed of an insulating material, a board support member 5, a fastening member 10, and a conductor pattern 6. A transformer 3 and a plurality of electronic components 4 are mounted on the insulating board 2. The conductor pattern 6 is formed on the principal surface 21 on the board support member 5 side in the insulating board 2. A part of the conductor pattern 6 is an intervention conductor pattern 6a interposed between the insulating board 2 and an upright portion 51. In at least one of the upright portion 51 and intervention conductor pattern 6a, a protrusion 71 protruding in the Z direction is formed, and a recess 72 in which the protrusion 71 is fitted is formed in the other. An alignment part 7 for aligning the insulating board 2 and upright portion 51 is formed by the protrusion 71 and recess 72. |
