To suppress peeling or deformation of a metal board bonded to an electrode formed in a PTC element.SOLUTION: A heating element comprises: an insulation substrate 57 to which an electrode is provided onto a front surface; a plurality of PTC elements 1 that is arranged onto the insulation substrate 57 along a predetermined arrangement direction, and in which the electrode is formed onto both main surfaces; and a metal board 56 that is bonded with an electrode 3 of the plurality of PTC elements 1 so as to be conducted, and is fixed to the insulation substrate 57. Each of electrodes 2 formed on one main surface side of the plurality of PTC elements 1 is connected to an electrode 55 of the insulation substrate 57 so as to be conducted. The metal board 56 includes: a flat plate part 561 that is connected to each electrode 3 formed on the plurality of PTC elements 1; leg parts 56a and 56b that are bent toward the insulation substrate 57 from the flat plate part 561, and are extended along a thickness direction of each PTC element 1; and fixing parts 56c and 56d that fix the leg parts 56a and 56b to the insulation substrate 57.SELECTED DRAWING: Figure 1 【課題】ＰＴＣ素子に形成された電極と接合される金属板の剥離や変形を抑制する。【解決手段】表面に電極が設けられた絶縁基板５７と、前記絶縁基板５７上に複数個、所定の配列方向に沿って配置され、両主面に電極が形成されたＰＴＣ素子１と、前記複数のＰＴＣ素子１の電極３と導通可能に接合され、前記絶縁基板５７に固定される金属板５６とを備え、複数の前記ＰＴＣ素子１の一方主面側に形成された各々の電極２は、前記絶縁基板５７の電極５５と導通可能に接続され、前記金属板５６は、複数の前記ＰＴＣ素子１の他方主面側に形成された各々の電極３と接続される平板部５６１と、前記平板部５６１から前記絶縁基板５７に向かって折り曲げられ前記ＰＴＣ素子１の厚み方向に沿って延びる脚部５６ａ、５６ｂと、前記脚部５６ａ、５６ｂを前記絶縁基板５７に固定する固定部５６ｃ、５６ｄとを有する。【選択図】図１
