description	A material which is excellent in mechanical strength, solar cell sealing properties, transparency, etc., even in an uncrosslinked state and is used in producing a sheet for solar cell sealing. The thermoplastic resin composition for solar cell sealing comprises (A) 0-70 wt. % propylene polymer having a melting point of 100° C. or higher and (B) 30-100 wt. % propylene copolymer satisfying the following requirements (b). (b) The copolymer has an MFR (230° C., 2.16-kg load) in the range of 0.01-100 g/10 min and satisfies at least one of the following requirements (b-1) and (b-2): (b-1) the rr content is 60% or higher; and (b-2) the copolymer comprises 55-90 mol % structural units derived from propylene and 10-45 mol % structural units derived from a C2-20 α-olefin (excluding propylene) and has an intrinsic viscosity [ ] (dL/g) (measured in 135° C. decalin) satisfying a specific relationship with the MFR.
