1. A semiconductor device, comprising:
a first electrode-lead having a first Au film, a first Ni film, a Cu film, a second Au film and a second Ni film stacked in order, the first electrode-lead having a first surface and a second surface on opposite sides;
a second electrode-lead having a first Au film, a first Ni film, a Cu film, a second Au film and a second Ni film stacked in order, the second electrode-lead disposed apart from the first electrode-lead, the second electrode-lead having a first surface and a second surface on opposite sides;
a semiconductor chip having a first electrode formed on a first surface of the semiconductor chip and a second electrode formed on a second surface of the semiconductor chip, the first electrode being formed on an opposite side of the second electrode, the semiconductor chip mounted on the first electrode-lead, the second electrode facing the first surface of the first electrode-lead;
a first connection conductor connecting the first electrode of the semiconductor chip to the first surface of the second electrode-lead; and
a package housing the first electrode-lead, the second electrode-lead and the semiconductor chip, the second surface of the first electrode-lead and the second surface of the second electrode-lead being exposed at a surface of the package.
