To provide a resin powder composition for slush molding which gives a molded body excellent in strength, while improving good melt fluidity during molding.

The resin powder composition for slush molding comprises a resin powder composition (E) which is any one of the following (1) to (3). (1) A resin powder composition (E1) comprising a polymer (A) having one or more acidic groups (a) in one molecule and a polymer (B) having one or more basic groups (b) in one molecule. (2) A resin powder composition (E2) comprising the polymer (A) and a compound (C) having two or more basic groups (b) in one molecule. (3) A resin powder composition (E3) comprising the polymer (B) and a compound (D) having two or more acidic groups (a) in one molecule.
