Abstract: A solar cell module is provided with a solar cell, a sealing member embedding the solar cell therein, a front surface protective member, and a back surface protective member. The storage modulus of the sealing member for the temperature range of 20-40° C. is from 6×107 Pa to 1×109 Pa (inclusive), and the average linear expansion coefficient, which is the average of linear expansion coefficients in the length direction and in the width direction when the temperature of the back surface protective member is changed from 20° C. to 25° C., is 40 ppm/° C. or less. A solar cell protective sheet is a laminate wherein an adhesive layer contains a (meth)acrylic polymer including functional groups reactive with carboxyl groups is laminated on the surface of a transparent resin sheet formed from at least one light-transmitting resin material selected from (meth)acrylic resins, polycarbonate resins and fluororesins.

Abstract: A method of manufacturing a stamper of the invention includes: performing a blast process on an aluminum base material, and thereafter anodizing a processing surface of the blast-processed aluminum base material so that a structure which includes a rough rugged structure having an specific arithmetic average roughness Ra and a specific period Sm and a fine rugged structure which is formed on the rough rugged structure to have a shorter period than that of the rough rugged structure is formed on a surface of the aluminum base material. In the stamper of the invention, by anodizing the processing surface of the blast-processed aluminum base material, the structure which includes the specific rough rugged structure and the fine rugged structure which is formed on the specific rough rugged structure to have a shorter period than that of the rough rugged structure is formed on the surface of the aluminum base material.
