Claim:
1. An electrostatic capacitance fluid level sensor comprising: a hermetic terminal having a metal base and two electrically conductive terminal pins inserted through the metal base to be hermetically insulated and fixed; a detection unit including two electrodes provided on the hermetic terminal for detection of fluid level by electrostatic capacitance and a spacer fixing the electrodes in a parallel relationship, the spacer being electrically insulative; and two connecting terminals configured to connect and fix the two conductive pins to the two electrodes respectively, wherein the connecting terminals are formed into such a shape as to include parts parallel to the electrodes and parts orthogonal to the electrodes by bending the connecting terminals at bends, respectively; wherein the parts parallel to the electrodes are welded and fixed to sides of the electrodes opposed to sides of the electrodes facing each other, respectively; wherein the parts orthogonal to the electrodes are connected and fixed to the conductive pins respectively; wherein the detection unit is disposed between the two conductive pins; wherein one of the two connecting terminals has a larger thickness than the other thereby to have a sufficient stiffness to hold the detection unit; and wherein at least one of the two connecting terminals is deformable by a weaker force than a force causing the electrodes to deform.
