PROBLEM TO BE SOLVED: To provide a resin composition containing stereocomplex polylactic acid, excellent in molding processability, having high crystallinity and having a high melting point, a production method thereof and a molded product. The present invention provides (A) a polylactic acid unit A in which L-lactic acid units are 90 mol% or more and 100 mol% or less, and (B) a poly (lactic acid unit) in which D-lactic acid units are 90 mol% or more and 100 mol% or less. It consists of lactic acid unit B, (A) and (B) have a weight ratio in the range of 10:90 to 90:10, a weight average molecular weight of 50,000 to 500,000, and a differential scanning calorimeter (DSC) measurement. , 40 to 98 parts by weight of stereocomplex polylactic acid having a melting peak ratio of 200% or higher of the melting peak in the temperature rising process of 80% or more, and 2 to 60 parts by weight of (C) filler, It is the resin composition to contain, its manufacturing method, and a molded article.
