Provided are a solar cell module and a solar cell module manufacturing method, the solar cell module being capable of maintaining a higher power generation capacity even if water infiltrates. In a solar cell module 10, in a first groove section 30, a second transparent conductive film 14a is in contact with a first transparent conductive film 12 while covering a side wall of a photoelectric conversion layer 13. A metal film 14b is in contact with the first transparent conductive film 12 while covering a side wall of the second transparent conductive film 14a. In the first groove section 30, the metal film 14b is in contact with the photoelectric conversion layer 13 while covering a side wall of the second transparent conductive film 14a formed on the photoelectric conversion layer 13.
