The therapeutic energy imparting structure 9 includes an insulating substrate 921, an electric resistance pattern 9222 provided on one surface of the insulating substrate 921, and an electric resistance pattern 9222 provided on the one surface and having an electric resistance A pair of lead wire connecting portions 9221 having a low value, and a heat transfer plate 91 arranged to face the one surface. The insulating substrate 921 and the heat transfer plate 91 are respectively formed in an elongated shape extending in the same direction. The electric resistance pattern 9222 and the pair of lead wire connecting portions 9221 are arranged side by side along the longitudinal direction of the insulating substrate 921. The width dimension W 1 on one end side of the insulating substrate 921 is larger than the width dimension W 2 on the other end side. The heat transfer plate 91 covers the entire area of the electric resistance pattern 9222, and one end in the longitudinal direction of the heat transfer plate 91 coincides with the boundary position BP 2 between the electric resistance pattern 9222 and the pair of lead wire connection portions 9221.治療用エネルギ付与構造9は、絶縁性基板921と、絶縁性基板921の一方の面に設けられた電気抵抗パターン9222と、当該一方の面に設けられ、電気抵抗パターン9222に比して電気抵抗値が低い一対のリード線接続部9221と、当該一方の面に対向して配設された伝熱板91とを備える。絶縁性基板921及び伝熱板91は、同一の方向に延びる長尺状にそれぞれ形成されている。電気抵抗パターン9222及び一対のリード線接続部9221は、絶縁性基板921の長手方向に沿って並んで配設される。絶縁性基板921の一端側における幅寸法W1は、他端側の幅寸法W2よりも大きい。伝熱板91は、電気抵抗パターン9222の全領域を覆い、当該伝熱板91の長手方向の一端が電気抵抗パターン9222及び一対のリード線接続部9221の境界位置BP2に一致する。
