PROBLEM TO BE SOLVED: To solve the conventional problems that a space by a length of a pivotal shaft is required when the pivotal shaft is protrudedly provided on mutually opposing both face of plug blades to hinder further reduction of size and weight of an AC adapter required by consumers' needs for the AC adapter. SOLUTION: This plug blade of the AC adapter is provided with a pair of plug blade fittings, a mold part molding basic parts of the pair of plug blade fittings and provided with mutually opposing first pivotal face and second pivotal face and a semicircular terminal barrel peripheral part, the pivotal shaft provided protrudedly on the first pivotal face, a contact part of the plug blade fitting provided protrudedly on the second pivotal face, and a pivotal part provided in the terminal barrel peripheral part. Furthermore, elastic contacts are erected by opposing mutually in a case, and the contact part is protrudedly provided at a position where the elastic contacts are apart from each other while the plug blades are stored in the case and come into mutual contact when the plug blades are pivotally moved and protrude.
