A piezoelectric device has a layered structure in which at least a first electrode, a plastic layer, an orientation control layer, a piezoelectric layer, and a second electrode are stacked, wherein the orientation control layer is amorphous, and the piezoelectric layer with a thickness of 20 nm to 250 nm is provided over the orientation control layer, the piezoelectric layer having a wurtzite crystal structure, and wherein the orientation control layer and the piezoelectric layer are provided between the first electrode and the second electrode.

Piezoelectric device with orientation control layer formed of sazo and manufacturing method thereof

Provided is an electromagnetic wave transmissive metal member capable of being easily produced at a low production cost, with both a metallic luster and an electromagnetic wave transmissibility, an article using the electromagnetic wave transmissive metal member, and a production method for an electromagnetic wave transmissive metal film. The electromagnetic wave transmissive metal member comprises a metal layer and a crack layer, wherein the metal layer and the crack layer have, in their respective planes, a plurality of linear cracks extending substantially parallel to each other. The linear cracks in the metal layer and the linear cracks in the crack layer penetrate through their respective layers in a thickness direction, and are continuous with each other in the thickness direction.
