PROBLEM TO BE SOLVED: To provide a liquid heating device whose short-circuit is prevented and that is made small.SOLUTION: The liquid heating device comprises a tank 4 for storing a liquid heat medium, an electric heater 3 housed in the tank 4 and heating the liquid heat medium, a transistor 10 for controlling a current supplied to the electric heater 3, a control substrate 21 that is connected to the transistor 10 and through which a control current to the transistor 10 flows, and a temperature switch 11 for detecting temperature in the tank 4 by a heat detection part 11a. The transistor 10 and the control substrate 21 are arranged on the tank 4. The temperature switch 11 is mounted to a tank upper face 4c while the heat detection part 11a is inserted in the tank 4. The control substrate 21 is arranged above the temperature switch 11 so that a distance from the transistor 10 is shorter than length of an end 10a of the transistor 10 and an insulation distance to an upper end of the temperature switch 11 is kept.

    【課題】短絡を防止し、かつ小型化した液体加熱装置を提供する。【解決手段】液状熱媒体を貯留するタンク4と、タンク4に収容され、液状熱媒体を加熱する電気ヒータ3と、電気ヒータ3へ供給される電流を制御するトランジスタ10と、トランジスタ10が接続し、トランジスタ10への制御電流が流れる制御基板21と、タンク4内の温度を熱検知部11aで検知する温度スイッチ11とを備え、トランジスタ10及び制御基板21は、タンク4上に配置され、温度スイッチ11は、熱検知部11aがタンク4内に挿入された状態で、タンク上面4cに取り付けられ、制御基板21は、トランジスタ10との距離がトランジスタ10の端子10a長さよりも短く、かつ温度スイッチ11の上端部との絶縁距離を保つように、温度スイッチ11の上方に配置される。【選択図】図3
