Abstract
A piezoelectric device includes an integrated circuit (IC) chip and a piezoelectric resonator element, a part of the piezoelectric resonator element being disposed so as to overlap with a part of the IC chip when viewed in plan. The IC chip includes: an inner pad disposed on an active face and in an area where is overlapped with the piezoelectric resonator when viewed in plan; an insulating layer formed on the active face; a relocation pad disposed on the insulating layer and in an area other than a part where is overlapped with the piezoelectric resonator element, the relocation pad being coupled to an end part of a first wire; and a second wire electrically coupling the inner pad and the relocation pad, the second wire having a relocation wire and a connector that penetrates the insulating layer, the relocation wire being disposed between the insulating layer and the active face.
