Abstract
A deformation detection sensor that includes a conductive member, a plurality of thermoplastic resin layers, and a piezoelectric film. At least one of the thermoplastic resin layers has a main surface, and the conductive member is formed on the main surface thereof. The plurality of thermoplastic resin layers are laminated and integrally formed by hot pressing into a laminated body. A transmission line is formed form a first portion of the conductive member and the thermoplastic resin in the laminated body. The piezoelectric film is attached to the laminated body to form a piezoelectric element made of a second portion of the conductive member, the thermoplastic resin in the laminated body, and the piezoelectric film.
