Abstract: The polylactic acid resin composition of the present invention includes a polylactic acid resin (A) having a D-isomer content of 0 to 2.0 mol % or 98.0 to 100 mol %. The polylactic acid resin composition of the present invention further includes tin oxide (B) in an amount of 0.005 to 10 parts by mass in relation to 100 parts by mass of the polylactic acid resin (A). By using the polylactic acid resin composition of the present invention, a molded body being excellent in crystallinity and heat resistance, and at the same time, having sufficiently excellent moisture-heat durability can be obtained.
