PROBLEM TO BE SOLVED: To provide a plug which has a long lifetime even in case the plug is severely used, and in which a satisfactory lifetime is obtained especially even in case the conductor cross sectional area of its electric wire cord is small. SOLUTION: This is the attachment plug covered by a resin molded body including the part connected with an insulated core wire of the electric wire cord in a state that two pairs of plug blades connected with the insulated core wire of the electric wire cord are prepared in parallel, and because the resin molded body is constituted of a hard resin-made inner molded body having a covering and a fixing part to individually cover and fix the connecting part with the conductor of the electric wire cord of the two pairs of plug blades and having a bridge to connect the fixing part bendably to each other, and constituted of a soft resin-made outer molded body to cover and fix the insulated core wire together with the inner molded body in the state that the insulated core wire is wound around the bridge, even if a strong external force is added between the plug blade and the electric wire cord, its force is alleviated by the bridge.
