A solar cell module comprises a plurality of solar cell elements including a front surface electrode and a wiring member electrically interconnecting the solar cell elements. The front surface electrode includes a bus bar electrode and finger electrodes, the finger electrodes including a plurality of first finger electrodes and connected to the bus bar electrode, and a plurality of second finger electrodes not connected to the bus bar electrode. The front surface electrode further includes a fine wire electrode that is disposed in a region extending from the bus bar electrode in a longitudinal direction of the bus bar electrode and that is electrically connected to the second finger electrodes, the fine wire electrode including first and second fine wire electrodes intersecting to each other. The wiring member is connected to an intersection of the first and second fine wire electrodes and to the bus bar electrode.

Solar cell module

A solar cell module manufacturing device is disclosed. The device includes a wire supply portion, a correction portion, and a cutting portion. The supply portion includes a bobbin and wiring material on the bobbin. The correction portion corrects curvature of the wiring material. The correction portion comprises a first pulley that comes in contact with the wiring material which is drawn from the bobbin. The first pulley comprises at a periphery thereof a first groove. The first groove comprises a first basal surface and a pair of first inclined surfaces which are arranged on both sides of the first basal surface. An inclination angle &#x3b8;1 of the first inclined surface relative to the first basal surface being less than or equal to an inclination angle &#x3b8;2 of the wiring material which is drawn from the supply portion relative to the first basal surface.
