1. A solar cell comprising:
a flexible base film;
a first power generation layer formed on one surface of the base film, configured to photoelectric convert incident light, and having a valid area contributing to power generation;
a first sealing resin layer covering at least the valid area of the first power generation layer;
a first protective insulating layer covering, on the one surface of the base film, at least a part of an invalid portion that is not covered with the valid area of the first power generation layer and having an elasticity higher than that of the first sealing resin layer; and
a first terminal electrode provided at a position overlapping the invalid portion of the one surface of the base film and electrically connected to the valid area of the first power generation layer.
