摘要： Provided are an fiber-reinforced plastic molding material having a satisfactory handling property, long storage stability, and high moldability enabling shaping into even a complicated shape, and a molded article thereof having excellent heat resistance, mechanical strength, and a method of producing the same. The fiber-reinforced plastic molding material includes a matrix resin containing, as an essential component, a phenoxy resin being solid at ordinary temperature and having a melt viscosity of 3,000 Pa·s or less at anywhere in the temperature region of from 160° C. to 220° C., with an epoxy resin and across-linking agent being blended as desired, in which the matrix resin is turned into fine powder having an average particle diameter (d50) of from 10 μm to 150 μm, and the matrix resin is caused to adhere to a reinforcing fiber base material by powder coating so as to achieve a resin content of from 20% to 50%.
