Claims

[Scope of utility model registration request]

A microwave transmission means consisting of a coaxial cable having a center conductor and an outer conductor, a microwave emitting section provided at the tip of the coaxial cable and electrically connected to the center conductor, and a surface of the microwave emitting section. It has an electrically insulating insulating layer, a biological electrode provided near the microwave emitting part and electrically connected to the external conductor, and a driving means for pressing the biological electrode against the biological body, The driving means presses the biological electrode against the affected area or the vicinity of the affected area to make it electrically conductive while emitting microwaves from the microwave emitting part to heat the affected area. Microwave probe for heating.
