Abstract

Disclosed is an electrostatic capacitative liquid surface sensor (1) wherein an electrode plate (7) for liquid surface detection is provided on a conductive pin (6) provided on a gas tight terminal (2). The liquid surface detection section provided on the gas tight terminal is constituted as a detection section unit (3) comprising two electrodes (7) and an electrically insulating spacer (8) whose positional relationship with the electrodes is fixed. At least one connecting terminal (9) whereby said detection section unit is fixedly connected to the conductive pin of the gas tight terminal is made to be capable of being deformed by a weaker force than would create deformation of said electrode. The stress acting on the detection section unit is dispersed/buffered by deformation of the connecting terminal and so can prevent deformation of the electrode constituting the detection section.
