PROBLEM TO BE SOLVED: To provide an electric heater including a film-shaped heater, in which the vibration at the end of the film-shaped heater is prevented.SOLUTION: An electric heater 1 includes a plurality of film-shaped heaters 13 and supporters 9a and 9b. Each of the plurality of film-shaped heaters 13 includes a pair of electrodes disposed on an electrically insulating film, and a heat generation layer that is stacked on the insulating film and electrically connects between the pair of electrodes. A bonding portion disposed discretely for each of the film-shaped heaters 13 is bonded to the adjacent film-shaped heater 13. A portion between the bonding portions in each of the film-shaped heaters 13, together with the adjacent film-shaped heaters 13, surrounds a plurality of passage holes 6 in which the gas to be heated flows. In a part or all of the film-shaped heaters 13, a plurality of end parts not bonded to another film-shaped heater 13 is held and kept between the supporters.SELECTED DRAWING: Figure 1A

    【課題】フィルム状ヒータの端部の振動を防止するフィルム状ヒータを用いた電気ヒータを提供する。【解決手段】電気ヒータ1は複数枚のフィルム状ヒータ13と支持体9a、9bとを備え、複数枚のフィルム状ヒータ13の各々は、電気絶縁性の絶縁フィルム上に配置された一対の電極と、絶縁フィルムに積層されて一対の電極間を導通させる発熱層とを備え、複数枚のフィルム状ヒータ13の各々に離散的に配置された接合部は、隣り合うフィルム状ヒータ13と接合されており、複数枚のフィルム状ヒータ13の各々における複数個の接合部の間の部分は、隣り合うフィルム状ヒータ13と共に、加熱対象の気体が流れる複数個の通路孔6を囲み、複数枚のフィルム状ヒータ13のうち一部または全部は、他のフィルム状ヒータ13と接合されていない複数個の端部が、支持体に挟まれて保持されている。【選択図】図1A
