Abstract: A solar cell is manufactured, which includes: a solar cell substrate including a semiconductor substrate, a p-type surface and an n-type surface exposed on a first principal surface, and a texture structure in a second principal surface; a p-side electrode disposed on the p-type surface; an n-side electrode disposed on the n-type surface; and an insulation layer formed on the first principal surface and isolating the p-side electrode and the n-side electrode from each other. The manufacturing method of the solar cell includes: forming an insulation film covering the first principal surface; forming the texture structure in the second principal surface; and removing part of the insulation film, thereby forming the insulation layer.
