A therapeutic energy applying structure includes: an insulating substrate an electric resistance pattern provided on one surface of the substrate to generate heat a connection portion provided on the one surface and configured to be electrically connected to the resistance pattern, the connection portion having a lower electric resistance than the resistance pattern and a heat transfer plate facing the one surface and configured to transfer the heat from the resistance pattern to body tissue. The substrate and the heat transfer plate have an elongated shape extending in a same direction. The resistance pattern and the connection portion are arranged side by side in a longitudinal direction of the substrate. The substrate has a first region on which the connection portion is provided and has a second region on which the resistance pattern is provided. A width of the first region is larger than a width of the second region.
