A solar cell element 70 includes a plurality of finger electrodes 21 and a bus bar electrode 22 on a surface thereof. A light diffuser 60 is provided in an outer circumferential region C1 of the surface. The light diffuser 60 includes first light diffusers 60a and 60b provided along the left side 74a and the right side 74b, and second light diffusers 60c and 60d provided along the upper side 74c and the lower side 74d. The widths w 1 and w 2 of the first light diffusers 60a and 60b in a transverse direction perpendicular to the left side 74a or the right side 74b, are smaller than the widths w 3 and w 4 of the second light diffusers 60c and 60d in a transverse direction perpendicular to the upper side 74c or the lower side 74d. |
