PROBLEM TO BE SOLVED: To provide an acrylic thermoplastic resin composition improved in hue and stability during melt molding. SOLUTION: The acrylic thermoplastic resin composition contains a methacrylic resin (A), a polyvinyl acetal resin (B) and a specified phosphite compound (C), wherein at least the methacrylic resin (A) forms a continuous phase, and in main dispersion peak temperatures of the acrylic thermoplastic resin composition, a main dispersion peak temperature Tα<SB>AP</SB>derived from the methacrylic resin (A) indicates a value between a main dispersion peak temperature (Tα<SB>A</SB>) of the methacrylic resin (A) alone and a main dispersion peak temperature (Tα<SB>B</SB>) of the polyvinyl acetal resin (B) alone.
