Liquid state detecting element and liquid state detecting sensor
First Claim
1. A liquid state detecting element comprising:
- a film portion made of a flexible insulating material and extending in a longitudinal direction; and
a pair of detecting electrodes juxtaposed to each other on a layer of said film portion and extending in said longitudinal direction,in which said detecting electrodes are for being immersed at least partially in a liquid to be measured, so that a state of said liquid is detected on a basis of an electrostatic capacity between said pair of detecting electrodes,wherein;
said liquid state detecting element further comprises reinforcing portions made of a conductive material and disposed on said layer of said film portion on an outer side of said detecting electrodes; and
said reinforcing portions include;
a grounding terminal for being connected with a ground line; and
a pair of parallel reinforcing portions extending in said longitudinal direction along side edges of said film portion so as to sandwich said pair of detecting electrodes.
