PROBLEM TO BE SOLVED: To provide: a coating agent for a back sheet for a solar cell module, excellent in adhesion to a back sheet base material for a solar cell module, weather resistance, electrically insulating properties, heat resistance and also bending resistance; a back sheet for a solar cell module, on which a surface protective film made of the coating agent for a back sheet is formed; a solar cell module having the back sheet for a solar cell module; and a solar cell having the solar cell module.SOLUTION: A coating agent for a back sheet for a solar cell module is a coating agent used on a surface of a back sheet for a solar cell module, and contains a coloring agent and a dispersing group-containing (meta) acrylic polymer having a number-average molecular weight of 3,000-200,000 and a glass transition temperature of -10 to 120°C. A solar cell module is provided with the back sheet for a solar cell module. A solar cell has the solar cell module. |
