Abstract
An interposer includes element mounting sections and terminal sections directly and partly formed on a surface of an aluminum film having the predetermined pattern. Each of the element mounting sections and the terminal sections has a laminated structure of an Ni film, an Pd film and an Au film. The interposer is formed with an AuSn layer on a predetermined region of a surface of each Au film in the element mounting sections. The interposer includes a protective film having optical permeability that directly covers a region of the surface of the aluminum film, which is out of contact with the element mounting sections and the terminal sections.
