In an electrostatic capacitance fluid level sensor (1) including fluid level detection electrode plates (7) mounted on conductive pins (6) mounted on a hermetic terminal (2), a fluid level detection part mounted on the hermetic terminal (2) is constituted into a detection unit (3) including two electrodes (7), electrically insulating spacers (8) fixing a positional relationship between the electrodes (7), and at least one connecting terminal (9) configured to connect and fix the detection unit (3) to the conductive pins (6). The connecting terminal (9) is deformable by a weaker force than a force causing the electrodes (7) to deform. As a result, stress applied to the electrodes (7) of the detection unit (3) is dispersed/relaxed. Since the detection unit (3) is further connected and fixed to the hermetic terminal (2) for a motor compressor, a work for mounting the sensor (1) to the hermetic motor compressor can be rendered easier as well as the handling of the sensor (1). |
