摘要

A light-receiving-surface-side electrode (13) is provided on one surface of a monocrystalline silicon substrate having a pn junction. The light-receiving-surface-side electrode (13) comprises elongated grid electrodes (13a) disposed extending in a first direction, and a bus electrode (13b) that is wider than the grid electrodes (13a), the bus electrode (13b) extending in a second direction that intersects the first direction. The bus electrode (13b) has cut-out sections (22) that are recessed inward in the first direction from the side surfaces aligned with the second direction. The ends of the grid electrodes (13a) on the bus electrode (13b) side are accommodated inside the cut-out sections (22) without overlapping the bus electrode (13b).
