It is an object of the present invention to provide a thermoplastic polymer containing a lactone ring structural unit having high heat resistance and colorless transparency, and having a high balance between toughness and fluidity, and a method for producing the same. . A thermoplastic polymer containing a lactone ring structural unit, and a molecular weight distribution (weight average molecular weight / number average molecular weight) obtained by gel permeation chromatography of the thermoplastic polymer is 2.1. A thermoplastic polymer in the range of ~ 10.0. Moreover, the manufacturing method of the thermoplastic polymer containing the lactone ring structural unit characterized by performing superposition | polymerization in a specific organic solvent.
