Abstract
The thermoplastic resin composition according to the present invention includes a thermoplastic resin (A), and a modified ethylene copolymer (B) dispersed and contained therein, wherein the modified ethylene copolymer (B) in the thermoplastic resin composition has an average dispersed particle aspect ratio of 1 to 3.5, and an average dispersed particle diameter of not more than 3 μm. The modified ethylene copolymer (B) is preferably a copolymer, modified with an unsaturated carboxylic acid or a derivative thereof, of ethylene with at least one monomer component selected from the group consisting of (i) olefin components except for ethylene, (ii) diene components and (iii) ester components having an ethylenically unsaturated group.
