A solar cell is configured to include: a substrate (); a conductive film () formed on the substrate (); a compound semiconductor layer () formed on the conductive film (), including a p-type semiconductor crystal containing an element of Group Ib, an element of Group IIIb, and an element of Group VIb; a n-type window layer () formed on the compound semiconductor layer (), having apertures (); and a n-type transparent conductive film formed on the n-type window layer () and on portions of the compound semiconductor layer () at the apertures of the n-type window layer (). The compound semiconductor layer () includes high-resistance parts (B), in portions of the compound semiconductor layer () in the vicinity of a surface thereof on a side opposite to the conductive film (), and the high-resistance parts (B) contain a n-type impurity doped in the p-type semiconductor crystal. The high-resistance parts (B) are located under the apertures () of the n-type window layer (), respectively.
