Abstract: 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 from a supply opening in an extrusion molder, and melting and kneading a resin composition including the polyolefin-based resin and the additive A in the cylinder, and a step of molding by extrusion the resin composition from a die in the extrusion molder into a sheet shape.

Abstract: An encapsulating sheet for solar cell for encapsulating a solar cell, in which, in a case in which a square sheet obtained by cutting the sheet so that a planar shape becomes a square shape is heated at the atmospheric pressure and 150° C. for 15 minutes and is thus thermally shrunk, when a length of one side of the square sheet before being thermally shrunk is represented by L, a direction in parallel with a first side is considered as a first direction, and a direction perpendicular to the first side is considered as a second direction, and in the thermally-shrunk square sheet, a shortest length in the first direction is represented by M1, and a shortest length in the second direction is represented by M2, 0?|(M1?M2)/L|?0.4 is satisfied.
