摘要：An object of the present invention is to provide a resin composition havingimproved heat resistance (high crystallinity) and transparency without impairing rigiditywhich a polylactic acid resin inherently has, and a molded article composed of the resincomposition. A polylactic acid resin composition of the present invention contains 100parts by weight of a polylactic acid compound (A) having a specific moiety represented bythe formula (1): -X—R—X- and having a weight average molecular weight (Mw) of 5,000 to500,000, 5 to 2,000 parts by weight of a lactic acid resin (B) and 0.1 to 10 parts by weightof at least one kind of a transparent nucleating agent (C) selected from carboxylic acidamides, aliphatic alcohols and aliphatic carboxylic acid esters. In the formula (1), XandXeach independently represent an oxygen atom, a sulfur atom or an NH group,

Rrepresents an aliphatic hydrocarbon group having a weight average molecular weight of25 to 50,000 without containing a ring structure, and the hydrocarbon group may containan oxygen atom, a nitrogen atom or a sulfur atom.
