PROBLEM TO BE SOLVED: To provide a heating electrode that enables proper thawing to be performed by suppressing overheating of a surface of an object to be heated and that is made of a lightweight and inexpensive pin electrode.SOLUTION: At least one of heating electrodes is an aggregate of a pin electrode 1 following along a shape of an object to be heated. A recess 6 or a heat insulation part made of a heat insulation material is partially formed at a tip 5 of the pin electrode brought into contact with the object to be heated.COPYRIGHT: (C)2015,JPO&INPIT【課題】被加熱物の表面の過加熱を抑制して良好な解凍ができ、且つ軽量で低コストのピン電極からなる加熱電極を提供する。【解決手段】加熱電極の少なくとも一方の電極が、被加熱物の形状に沿って追従するピン電極1の集合体であり、被加熱物と接触するピン電極の先端部5に部分的に凹部6又は断熱材からなる断熱部を形成した。【選択図】図1
