    • A solar cell according to the present invention includes: a photoelectric conversion part having a photoelectric converting function; and a collector electrode provided at a side of a light-receiving surface of the photoelectric conversion part in a way that parts of the light-receiving surface are exposed. Interconnection tabs are connected at a side of a light-receiving surface of the collector electrode with an adhesive being interposed in between. The collector electrode contains a thermosetting first resin, an conductive material and a second resin for forming a sea-island structure between the second resin and the first resin. The collector electrode includes an internal region in the inside, a concentration ratio of the second resin to the first resin being higher in the internal region than in the surface region at the side of either the adhesive or the photoelectric conversion part.
