PROBLEM TO BE SOLVED: To provide a bayonet plug of which connection terminal blades will not easily be damaged even when they are plugged in and drawn out a power receptacle and which can be used for long time without trouble of a tracking phenomenon. SOLUTION: A plug main body 1, and at least a pair of connection terminal blades 2 with one end side 12 supported inside the plug main body 1 and the other end side 22 protruded outside are provided. The connection terminal blades 2 have peripheral concave parts 5 formed from an inner part of the plug main body 1 toward the root of an outward exposed part 20, and a heat-resistant insulating film 6 is coated on the concave part 5 in a buried state. It is so constructed that the surface of a concave unprocessed part 8 where the concave parts 5 are not formed on the connection terminal blades 2 and the surface of the heat-resistant insulating film 6 make up a continuous flat plane.
