Abstract

A solar cell includes: first and second conductivity type diffusion layers which are formed on a backside of a light-receiving surface of a substrate, first and second electrode portions, first and second electrode line portions, and first and a second electrode bus bar portions; a first insulator film which is formed to cover a side portion and a top of the second electrode portion in an intersection region of the second electrode portion and the first electrode bus bar portion, a second insulator film which is formed to cover a side portion and a top of the first electrode portion in an intersection region of the first electrode portion and the second electrode bus bar portion, wherein the second electrode portion is formed continuously in a line shape under the first insulator film, and the first electrode portion is formed continuously in a line shape under the second insulator film.
