Provided is a primer for a solar cell module which makes it possible to prevent peeling of a surface protective material from a sealing material over a long time, and a solar cell module manufactured using this primer. The primer includes 40 to 95 parts by mass of a polymerizable ester, 5 to 60 parts by mass of an adhesion promoter, and a polymerization initiator. The polymerizable ester includes at least one of an acryloyl group and a methacryloyl group. The adhesion promoter includes a functional group improvable is adhesion to an acrylic resin or a methacrylic resin, and an alkoxysilyl group. The polymerization initiator is configured to be able to initiate polymerization of the polymerizable ester. The content of the polymerization initiator is 0.1 to 10 parts by mass based on 100 parts by mass as a total of the polymerizable ester and the adhesion promoter.
