PURPOSE:To suitably perform heating to a joint part without generating unevenness of heating, so as to cope with various shaped joints with little leakage of microwave. CONSTITUTION:In a microwave hating-type plastic pipe fusing device for mutually welding plastic pipes to each other by irradiating microwave to a joint part C for plastic pipes A, B containing materials for generating heat after absorbing microwave, a microwave radiator 7 is arranged on one focal point on a rotational elliptical surface of a concave reflector 1 formed by the rotational elliptical surface. A microwave absorbing member 9 is arranged in the position facing the concave reflector 7. The joint part C for plastic pipes is arranged on the other focal point of the rotational elliptical surface of the concave reflector 1, and microwave is radiated to the joint part. |
