Abstract
A piezoelectric device includes a first substrate having a piezoelectric element on one surface thereof and a second substrate having penetration wiring that includes a through hole formed in a thickness direction thereof and a conductor section formed in the through hole. A resin section is formed on a surface of one substrate of one of the first substrate and the second substrate, which opposes the other substrate, and is formed of an elastic body in a shape protruding toward the other substrate, and a first electrode layer is formed on the surface of the other substrate side of the resin section. A second electrode layer is formed on a surface of the other substrate that opposes the one substrate, and the first substrate and the second substrate are joined in a state in which the first electrode layer and the second electrode layer are abutting against each other.
