Abstract
The finger electrode is formed by hard-soldered silver paste. The melting point of the first type solder layer provided on the surface of the terminal wiring member is higher than the melting point of the second type solder layer provided on the surface of the wire. The first width, in the first direction, of the second type solder layer in the first portion where the wire is connected to the terminal wiring member is larger than the second width, in the first direction, of the second type solder layer in the second portion where the wire is connected to the finger electrode.
