摘要： In a solar battery module including a plurality of solar battery elements each including electrodes that are electrically connected by an electrically conductive wiring member, the electrode and the wiring member are welded by solder on the electrode, resin is arranged while covering at least a side surface of a solder-bonded portion between the solder and the electrode, and a wetted height of the resin on a side surface of the wiring member is lower than the top of wiring member, so that welding by the solder can be reinforced and the bonding reliability can be improved.

摘要： A plurality of thin linear thin wire electrodes are formed entirely over a first surface that is a light receiving surface of a solar cell element, a back surface collecting electrode is formed on a second surface that is a back surface of the solar cell element, and a wiring member which draws power is connected to each of the thin wire electrode and the back surface collecting electrode. The thin wire electrode and the wiring member are bonded with solder and side surfaces of the solder bonding portion in a longitudinal direction along the wiring member are coated with a thermosetting resin, and, in a region excluding the thin wire electrodes, the wiring member and the first surface are bonded with a thermosetting resin. The wiring member and the thin wire electrodes are bonded to have a sufficient mechanical bonding strength and high bonding reliability.
