Disclosed is a solar cell having a collecting electrode 7 on one main surface of a photoelectric conversion section 50. The collecting electrode 7 includes a first electroconductive layer 71 and a second electroconductive layer 72 in this order from the photoelectric conversion section 50 side, and further includes an insulating layer 9 between the first electroconductive layer 71 and the second electroconductive layer 72. The first electroconductive layer 71 includes a low-melting-point material, and a part of the second electroconductive layer 72 is conductively connected with the first electroconductive layer 71 through, for example, an opening in the insulating layer. The second electrode layer is preferably formed by a plating method. In addition, it is preferable that before forming the second electroconductive layer, annealing by heating is carried out to generate the opening section in the insulating layer. |
