Abstract
A piezoelectric coaxial sensor includes: a sensor portion including a center conductor having a linear shape, a polymer piezoelectric layer containing polyvinylidene fluoride and that covers an outer peripheral surface of the center conductor, and a first outer conductor that surrounds an outer peripheral surface of the polymer piezoelectric layer; and jacket layers that each include a film having a tape shape wound to surround an outer peripheral surface of the sensor portion. The film of at least one of the jacket layers exposed to the outside of the piezoelectric coaxial sensor among the other jacket layers is adhered to a member in contact with an adhesive layer by the adhesive layer. The adhesive layer includes a thermoplastic resin having a melting point of 120° C. or lower.
