The present invention uses a plastic film which is excellent in electrical insulation, heat resistance and dimensional stability, and excellent in all properties such as mechanical strength, weather resistance, and water resistance, and by using an adhesive for two-component laminate having excellent weather resistance, even in a high temperature and high humidity environment. Provided is a back protective sheet for a solar cell module having excellent adhesive strength and breaking strength. As a base film, it improves weather resistance (hydrolysis resistance), and adds weather resistance (hydrolysis resistance) to the two-component laminate adhesive bonded thereto to provide excellent adhesive strength and breaking strength for a long time even in a high temperature and high humidity environment.
