The present invention relates rapid destruction of the sweat glands by the supply of thermal energy, safely and easily can be carried out, to provide an antiperspirant device capable of effectively suppressing the excessive sweating. A and the electrode needle 10 for supplying the thermal energy from the distal end portion 10a to puncture the target tissue, including sweat glands, inserting the needle electrode 10 has a cooling portion 24b on the surface side can be through-hole 28 but to have been formed cooling member 20, a support 30 for the needle electrode 10 movably accommodating the electrode needle 10 supports a cooling member 20 so as to be inserted into the through hole 28, is inserted into the through hole 28 antiperspirant apparatus 1 and a drive means 40 for retractable tip portion 10a from the cooling section 24b by advancing and retracting the electrode needle 10.【課題】 熱エネルギーの供給による汗腺の破壊を迅速、安全且つ容易に行うことができ、過剰な発汗を効果的に抑制することができる発汗抑制装置を提供する。【解決手段】 汗腺を含む標的組織に穿刺して先端部10aから熱エネルギーを供給する電極針10と、表面側に冷却部24bを有し電極針10を挿通可能な貫通孔28が形成された冷却部材20と、電極針10を移動可能に収容し電極針10が貫通孔28に挿入可能となるように冷却部材20を支持する支持体30と、貫通孔28に挿入された電極針10を進退させることにより先端部10aを冷却部24bから出没させる駆動手段40とを備える発汗抑制装置1。
