A thin film solar cell module of see-through type having cells connected in series and disposed on an opaque substrate with holes is provided. The thin film solar cell module includes a first electrode, a second electrode, and a photoelectric conversion layer disposed between the first electrode and the second electrode. The first electrode is disposed on the opaque substrate and is composed of a first comb electrode and block-like first electrodes. The second electrode is disposed above the first electrode and is composed of a second comb electrode and block-like second electrodes. A portion of the block-like first electrodes, a portion of the opaque substrate, and the holes are exposed between the second comb electrode and the block-like second electrodes. The second comb electrode and the first comb electrode are disposed symmetrically, and the block-like first electrodes and the block-like second electrodes are disposed by parallel displacement.
