Patent ID: 8264128

Claim:
A piezoelectric component comprising: a piezoelectric substrate; a piezoelectric device formed on a principle surface of said piezoelectric substrate; a device wiring section formed on a principle surface of said piezoelectric substrate; a protective film that has a terminal electrode connected to the wiring section and is formed on an upper surface of said wiring section; a rewiring layer that is formed on an upper surface of the protective film and that is connected to a wiring section of an electrode, which is different from said electrode; a buffer layer that is composed of an inorganic material and that covers the entire upper surface of the rewiring layer excluding said piezoelectric device; an outer periphery wall layer that is composed of a photosensitive resin and is formed on the upper surface of the buffer layer; a first ceiling layer that is composed of a photosensitive resin film and is formed on an upper surface of the outer periphery wall layer; a mesh-shaped member that is composed of an insulating material and is installed on an upper surface of the first ceiling layer; a second ceiling layer that is composed of a photosensitive resin film and is formed so as to cover an upper surface of the mesh-shaped member; and a through electrode that is formed so as to pass through said first ceiling layer, said second ceiling layer, said outer periphery wall layer, and said mesh-shaped member, wherein between said outer periphery wall layer, said first ceiling layer, and a principle surface of said piezoelectric substrate, there is formed a hollow section that accommodates said piezoelectric device.
