<P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition that causes no bleeding out though it contains coffee grounds, and a manufacturing method of a molded article of the same. Ž<P>SOLUTION: The manufacturing method of the thermoplastic resin composition comprising coffee grounds as a filler comprises a mixing step for mixing a thermoplastic resin with coffee grounds having a lipid content of at most 2 wt.% at a mixing ratio of 95:5 to 50:50 by dry weight. The coffee grounds are obtained from fermented coffee grounds subjected to a methane fermentation treatment as a main raw material while the thermoplastic resin is mainly composed of reclaimed polypropylene. The fermented coffee grounds contain at least 30 wt.% of water and the heating temperature in the mixing step is 40-280°C. Thus, the obtained molded article is prevented from bleeding out and exhibits enhanced toughness. Thus, a new application for coffee grounds that have been disposed of as industrial wastes is provided to contribute to recycling and reduction of environmental loads.
