To provide a solar battery cell module using solar cells of which the solar cell module can be composed without performing patterning including scribing on the entire electrode film etc., formed over the entire surface of one surface side of a substrate.

The solar battery cell module is constituted by electrically and serially connecting a plurality of solar battery cells 10, each formed by laminating an electrode film 14, a p-type semiconductor layer 16, an n-type semiconductor layer 18, and a transparent electrode 20 on one surface side of the substrate 12 in this order. The plurality of solar cells 10 are arranged in series; an extension electrode film 14a which is extended from the electrode film 14 and in an exposed state is formed on one of both flanks of the substrate 12, which face flanks of other solar cells 10 and 10 disposed adjacently to a solar battery cell 10 on both sides thereof; an extension transparent electrode 20a which is extended from the transparent electrode 20 without coming into contact with the electrode surface 14a is formed on the other flank; and the extension electrode film 14a of the solar cell 10 and extension transparent electrodes 20a of the adjacent solar battery cells 10 are electrically connected.
