To provide a heater element with which electrodes are hardly corrodible even in a water-existing environment, and with which it is possible to suppress the occurrence of shorting.SOLUTION: Provided is a heater element 100 comprising: a honeycomb structure 10 in which a bulkhead 14 is composed of a material having PTC characteristic; a first electrode 20 that has an electrode portion A1 provided on a first end face 12a and an electrode portion B1 conned to the electrode portion A1 and provided on the surface of the bulkhead 14 in a direction in which a passage extends from the first end face 12a; and a second electrode 30 that has an electrode portion A2 provided on a second end face 12b and an electrode portion B2 conned to the electrode portion A2 and provided on the surface of the bulkhead 14 in a direction in which a passage extends from the second end face 12b. A distance L1 between the electrode portion B1 and the electrode portion B2 is 30-97% of a length L3 of the honeycomb structure 10 in the direction in which the passage extends.SELECTED DRAWING: Figure 1A

    【課題】水分が存在する環境下であっても電極が腐食し難く、ショートの発生を抑制できるヒーターエレメントを提供する。【解決手段】隔壁14がPTC特性を有する材料で構成されたハニカム構造体10、第1端面12a上に設けられた電極部分A1と、電極部分A1に連結しており且つ第1端面12aから流路の延びる方向において隔壁14の表面に設けられた電極部分B1とを有する第1電極20、及び第2端面12b上に設けられた電極部分A2と、電極部分A2に連結しており且つ第2端面12bから流路の延びる方向において隔壁14の表面に設けられた電極部分B2とを有する第2電極30を備えるヒーターエレメント100である。電極部分B1と電極部分B2との間の距離L1が、ハニカム構造体10の流路の延びる方向の長さL3の30~97%である。【選択図】図1A
