Liquid state detecting element and liquid state detecting sensor

A liquid state detecting sensor comprising:

• a liquid state detecting element including:
• a film portion made of a flexible insulating material and extending in a longitudinal direction;
• a pair of detecting electrodes juxtaposed to each other on a layer of said film portion and extending in said longitudinal direction;
• and reinforcing portions made of a conductive material and disposed on said layer of said film portion on an outer side than said detecting electrodes;
• and
• a supporting member for supporting said liquid state detecting element,
• in which, by immersing at least a portion of said liquid state detecting element in a liquid to be measured, said detecting electrodes are immersed at least partially in the measured liquid, so that a state of said measured liquid is detected on a basis of an electrostatic capacity between said pair of detecting electrodes, wherein:
• said supporting member includes supporting portions for supporting a surface and a back face of said film portion, said reinforcing portions include a pair of parallel reinforcing portions extending in said longitudinal direction, and said liquid state detecting element is supported by arranging said pair of parallel reinforcing portions, at least partially overlapped by said supporting portions.
