摘要：
A method for manufacturing an encapsulating material sheet for a solar battery of the invention includes a step of producing an additive-containing pellet by soaking an additive A into a pellet including a polyolefin-based resin as a main component, a step of injecting the additive-containing pellet into a cylinder (103) from a supply opening (101) in an extrusion molder (100), and melting and kneading a resin composition including the polyolefin-based resin and the additive A in the cylinder (103), and a step of molding by extrusion the resin composition from a die (109) in the extrusion molder (100) into a sheet shape.
