Document Type and Number:
WIPO Patent Application WO/2021/182208
Kind Code:
A1
Abstract:
A piezoelectric coaxial sensor (1) comprises: a sensor unit (S) having a linear central conductor (11), a polymer piezoelectric layer (12) that includes polyvinylidene fluoride and covers the outer peripheral surface of the central conductor (11), and a first outer conductor (13) surrounding the outer peripheral surface of the polymer piezoelectric layer (12); and at least one jacket layer having a tape-shaped film that is wound so as to surround the outer peripheral surface of the sensor unit (S), wherein the film in the jacket layer exposed to the outside, among the jacket layers, is adhesively bonded by an adhesive layer composed of a thermoplastic resin having a melting point of 120°C or lower to a member in contact with the adhesive layer.
