Patent ID: 7945965

Claim:
A sensor for observing a sample in a liquid, comprising: a self-detecting probe having a probe tip located at its front end and placed opposite to the sample to be observed, a cantilever having a base end supported to a body portion of the probe, a strain resistive element formed over the cantilever and having a resistance value varying according to an amount of displacement of the cantilever, and interconnects electrically connected with the strain resistive element and extending from the cantilever to over the body portion; an elongated, belt-like flexible substrate having an interconnect pattern sealed between two insulating sheets, the flexible substrate supporting the body portion while the cantilever protrudes outwardly, the flexible substrate having at least one end brought out of the liquid, the flexible substrate having external contacts exposed to the outside at said one end brought out of the liquid; connecting members electrically connecting said interconnects with said interconnect pattern; and an insulating resinous portion with which said interconnects, said connecting members, and portions of the connecting members electrically connected with the interconnect pattern are coated.
