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