To detect the conductivity by utilizing a structure of a water level sensor.SOLUTION: Disclosed is a water level and conductivity detecting device which includes a reference electrode (110) to be inserted into a tank in which the liquid should be stored and one or more detection electrodes, and detects the water level in the tank by detecting the presence or absence of continuity between the reference electrode and one or more detection electrodes. One or more detection electrodes includes an object detection electrode (111) covered with an insulator. An electrode portion (110a) other than the reference exposure part (110b) including the lower end of the reference electrode among the reference electrodes and an electrode portion (111a) other than a detection exposure part (111b) including the lower end of the object detection electrode among the object detection electrodes are covered with the insulator, and the conductivity of the liquid in the tank is detected using the reference electrode and the object detection electrode.SELECTED DRAWING: Figure 11 【課題】水位センサの構造を利用して導電率も検出する。【解決手段】液体が収容されるべきタンクに挿入される基準電極（１１０）及び１以上の検出電極を備え、基準電極と１以上の検出電極との間の導通の有無を検出することでタンク内の水位を検出する水位及び導電率検出装置であって、１以上の検出電極は絶縁体で覆われる対象検出電極（１１１）を含み、基準電極の内、基準電極の下端を含む基準露出部（１１０ｂ）以外の電極部分（１１０ａ）と、対象検出電極の内、対象検出電極の下端を含む検出露出部（１１１ｂ）以外の電極部分（１１１ａ）と、が絶縁体で覆われ、基準電極及び対象検出電極を用いてタンク内の液体の導電率を検出する。【選択図】図１１
