Piezoelectric device, liquid ejecting head and method for manufacturing piezoelectric device

A piezoelectric device comprising:

• 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,
• wherein 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,
• wherein a second electrode layer, which is electrically connected to the first electrode layer, is formed on a surface of the other substrate that opposes the one substrate,
• wherein 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, and
• wherein a part of the resin section protruding toward the second electrode layer is disposed between the one substrate and the first electrode layer.
