NOVELTY - A solar cell module comprises a solar cell that comprises a photoelectric conversion body (5) and a fine line-shaped electrode (4A) formed on a light receiving surface (S) of the photoelectric conversion body, where the electrode extends in a first direction; and a sealing material provided on a light entering side of the solar cell. The solar cell comprises a low-refractive-index layer (8) disposed between a light receiving surface of the electrode and the sealing material, and provided to cover the light receiving surface of the electrode.    USE - A solar cell module.    ADVANTAGE - The solar cell module has improved output characteristics and high reliability.    DETAILED DESCRIPTION - A solar cell module comprises a solar cell that comprises a photoelectric conversion body (5) and a fine line-shaped electrode (4A) formed on a light receiving surface (S) of the photoelectric conversion body, where the fine line-shaped electrode extends in a first direction; and a sealing material (105) provided on a light entering side of the solar cell. The solar cell comprises a low-refractive-index layer (8) disposed between a light receiving surface of the fine line-shaped electrode and the sealing material. The low-refractive-index layer is provided to cover the light receiving surface of the fine line-shaped electrode. It has a refractive index lower than a refractive index of the sealing material; and an inclined surface (8S), whose central portion projects in a cross section of the low-refractive-index layer taken along a second direction perpendicular to the first direction. The cross section of the low-refractive-index layer becomes wider toward the light receiving surface of the photo-electric conversion body.
