The first area has first and second surfaces facing each other, and a cavity structure of the second area includes a cavity space; a contact surface; and a side wall. The contact surface is disposed opposite to the opening of the cavity structure. A value of a surface roughness of the contact surface is approximately three times or less of a value of a surface roughness of the first surface of the first area.
