PROBLEM TO BE SOLVED: To provide a disconnection detector which has a simple structure.SOLUTION: A disconnection detector 20 includes a detection circuit 13 which turns on or turns off a second ground switch 26 while fixing a first detection switch 21 in an on-state and fixing a second detection switch 22 and a first ground switch 25 in an off-state and determines whether there is a disconnection in a first detection line 15 according to whether the capacitance change amount detected by the turning-on or turning-off corresponds to a preset value.SELECTED DRAWING: Figure 3

    【課題】構成が簡素な断線検出装置を提供する。【解決手段】断線検出装置20は、第1検出スイッチ21をオン、第2検出スイッチ22をオフ、及び第1グランドスイッチ25をオフにそれぞれ固定した状態で、第2グランドスイッチ26のオンオフを切り替え、当該切り替えにより検出される静電容量変化量があらかじめ設定される設定値に対応するか否かを通じて、第1検出線15における断線の有無を判定する検出回路13を備える。【選択図】図3
