To provide a vehicular electric heater capable of controlling an electrification amount of respective heating bodies in every finer region than a conventional electric heater.SOLUTION: An electric heater 10 comprises a first heating body group 122, a second heating body group 122, a control part 18, a first multilayer substrate, and a second multilayer substrate. The first heating body group 122 has three heating bodies 122a, 122b and 122c supported by a resin frame. The second heating body group 122 has three heating bodies 122a, 122b and 122c supported by a resin frame different from that of the first heating body group 122. The first multilayer substrate electrically connects the three individual heating bodies of the first heating body group 122 to the control part 18. The second multilayer substrate electrically connects the three individual heating bodies of the second heating body group 122 to the control part 18. The control part 18 individually controls electrification amounts of the three heating bodies of the first heating body group 122 and electrification amounts of the three heating bodies of the second heating body group 122.SELECTED DRAWING: Figure 2

    【課題】従来の電気ヒータよりも細かな領域毎に、各発熱体の通電量を制御できる車両用電気ヒータを提供する。【解決手段】電気ヒータ10は、第1発熱体群122と、第2発熱体群122と、制御部18と、第1多層基板と、第2多層基板とを備える。第1発熱体群122は、樹脂枠に支持された3つの発熱体122a、122b、122cを有する。第2発熱体群122は、第1発熱体群122とは別の樹脂枠に支持された3つの発熱体122a、122b、122cを有する。第1多層基板は、第1発熱体群122の3つの発熱体のそれぞれを個別に制御部18に電気的に接続する。第2多層基板は、第2発熱体群122の3つの発熱体のそれぞれを個別に制御部18に電気的に接続する。制御部18は、第1発熱体群122の3つの発熱体のそれぞれの通電量および第2発熱体群122の3つの発熱体のそれぞれの通電量を個別に制御する。【選択図】図2
