The heat generating structure (first electrode portion) described in Patent Document 1 includes a heater (electric heat conversion element), a heat transfer plate (first high frequency electrode), and an adhesive member (high thermal conductive heat resistant adhesive sheet) described below. Prepare.
The heater is a seat heater having an electric resistance pattern formed on one surface of the substrate (hereinafter, referred to as a first main surface) to generate heat by energization.
The heat transfer plate is made of a conductive material such as copper. The heat transfer plate has a second main surface opposite to the first main surface, and transfers the heat from the electrical resistance pattern to the living tissue (heat energy is applied to the living tissue).
The adhesive member is a sheet having good thermal conductivity and electrical insulation. The bonding member is interposed between the first and second main surfaces to bond and fix the heater and the heat transfer plate.
