A piezoelectric device includes a substrate that is flexible and thermally deformable, and a composite piezoelectric body disposed on the substrate. Output in accordance with deformation of the composite piezoelectric body is obtained. The composite piezoelectric body includes a piezoelectric layer containing an organic binder containing piezoelectric particles, a first electrode layer stacked on a first surface side of the piezoelectric layer, and a second electrode stacked on a second surface side of the piezoelectric layer. The substrate is insert molded and integrated with a molded resin body having a curved shape.
