The therapeutic energy application structure 9 includes an electric resistance pattern 9222 that generates heat when energized, and a flexible substrate 92 in which a lead wire connection portion 9221 that is connected to the electric resistance pattern 9222 and is connected to the lead wire C1 is formed on one surface. Between the flexible substrate 92 and the heat transfer plate 91, and the heat transfer plate 91 that is disposed to face the one surface and that contacts the living tissue and transfers heat from the electrical resistance pattern 9222 to the living tissue. It is provided with an insulating adhesive sheet 93 that is interposed and that adheres and fixes the flexible substrate 92 and the heat transfer plate 91. The adhesive sheet 93 includes a first region Ar1 that covers at least the entire surface of the electric resistance pattern 9222 of the heat transfer plate 91, and a second region Ar2 that projects from the heat transfer plate 91 and covers a part of the lead wire connection portion 9221. The heat transfer plate 91 is chamfered at a corner portion that contacts the adhesive sheet 93.治療用エネルギ付与構造９は、通電により発熱する電気抵抗パターン９２２２と、当該電気抵抗パターン９２２２に導通するとともにリード線Ｃ１が接続されるリード線接続部９２２１が一方の面に形成されたフレキシブル基板９２と、当該一方の面に対向して配設され、生体組織に接触して電気抵抗パターン９２２２からの熱を生体組織に伝達する伝熱板９１と、フレキシブル基板９２及び伝熱板９１の間に介装され、フレキシブル基板９２及び伝熱板９１を接着固定する絶縁性の接着シート９３とを備える。接着シート９３は、少なくとも伝熱板９１の電気抵抗パターン９２２２全面を覆う第１領域Ａｒ１と、伝熱板９１から張り出すとともにリード線接続部９２２１の一部を覆う第２領域Ａｒ２とを有する。伝熱板９１は、接着シート９３に当接する角部分が面取りされている。
