Abstract: A method of manufacturing a thermoplastic resin for a household plumbing equipment includes: reacting an acid component including a terephthalic acid and a glycol component including a trimethylene glycol derived from a plant to form a poly trimethylene terephthalate resin as a condensation polymer of a formed glycol ester; and combining the poly trimethylene terephthalate resin with a polymethyl methacrylate resin in a mass ratio of 90:10-50:50 to form a thermoplastic resin, wherein the thermoplastic resin includes the polymethyl methacrylate resin and the polytrimethylene terephthalate resin in an amount of 80% or more by mass of a total amount of the formed thermoplastic resin.
