  • Publication number: 20080136020
    Abstract: A first electronic circuit component and a second electronic circuit component are electrically connected to an electro-conductive member via a first solder and a second solder, respectively. The electro-conductive member is formed in a resin film. The electro-conductive member is configured as containing a second diffusion barrier metal film. The second diffusion barrier metal film prevents diffusion of the second solder. Between the electro-conductive member and the first solder, a first diffusion barrier metal film is provided. The first diffusion barrier metal film prevents diffusion of the first solder. On the first surface of the resin film and on the electro-conductive member, an adhesive metal film is formed so as to contact with the resin film and the electro-conductive member. The adhesive metal film has stronger adhesiveness to the resin film than either of those of the first solder and the first diffusion barrier metal film.
