PROBLEM TO BE SOLVED: To provide an AC adaptor capable of stabilizing contact pressure between a contact terminal and a primary plug, facilitating assemblage, and eliminating work irregularity. SOLUTION: A pair of contact terminals 7, 7 disposed on a power source circuit board 6 are made of copper phosphate, and are U-shaped. A connection part 7a is positioned on the end part side of the power source circuit board 6, a lower part is connected to a power transformer, for example, and a contact part 8 is set to be in linearly contact with an upper part 7b. At this time, since the contact terminals 7, 7 are made of copper phosphate, and are U-shaped, an upper part 7a is pressed downward, and a sufficient contact pressure can be provided. Because of a large contact surface, stable contact can be achieved.
