It is aimed to provide a solar cell element and a solar cell module capable of reducing an output drop in a case where a crack occurs in the solar cell element. In order to achieve this object, the solar cell element includes a substrate body including a photoelectric conversion part, a plurality of first electrodes located at intervals on one main surface of the substrate body, and a crack guiding part located in a region positioned between a pair of adjacent first electrodes among the plurality of first electrodes when the substrate body is viewed or viewed through in plan view from the one main surface side and configured to guide a position of a crack occurring in the substrate body upon application of a load to the substrate body.
