摘要: A piezoelectric device ensures resistance to molding without an increase in costs and includes elemental substrate having a element conductive pattern electrically connected the element; insulating members disposed on surrounding leaving space around element. The have internal conductor extending apart from substrate. has expanded portions expanding direction intersecting wiring of or detour portion deviating direction. crosses boundary sealed formed
