PROBLEM TO BE SOLVED: To provide a tab electrode hardly separated from a solar battery cell and capable of being reduced in optical loss with respect to a solar battery cell, and a solar battery module high in photoelectric conversion efficiency.SOLUTION: A tab electrode comprises a flat body formed by rolling stranded wires or the like made of a plurality of metal element wires, and has a surface roughness (Ra) of a reflection surface of 2.0-5.0 μm. A solar battery module includes: a plurality of solar battery cells in each of which a collector electrode is formed on a light incident surface side thereof; the tab electrode connected between the collector electrodes of solar battery cells adjacent to each other; and a light transmitting member arranged on a light incident surface side of the solar battery cells.SELECTED DRAWING: Figure 1 |
