A method of the invention can produce a fiber-reinforced thermoplastic resin foamed product having less unevenness in a thickness of a surface layer and excellent mechanical strength. In the method, a fiber-reinforced thermoplastic resin sheet is continuously shaped into a hollow member, and a foaming resin composition containing a thermoplastic resin and a foaming agent is supplied into an interior of the obtained hollow member. The foaming agent is foamed so that the hollow member is shaped into a desired form by the foaming pressure.
