This invention is characterized by including: a step for forming an n-type silicon substrate (1) having a p-n junction, and forming a p-type diffusion layer (2) on one main surface side of the n-type silicon substrate (1); a step for forming a layered film of a silicon oxide film (5) and a silicon nitride film as a passivation film on one of the first and second main surfaces of the n-type silicon substrate, on the n-type light-receiving surface (1A) side; a step for forming apertured regions (9) in the passivation film; a step for diffusing an n-type impurity and forming high-concentration diffusion regions (11) by using the passivation film as a mask for the apertured regions (9) of the passivation film; and a step for selectively forming metal electrodes (13) in the high-concentration diffusion regions (11) exposed in the apertured regions (9) of the passivation film.
