Abstract
An object of the present invention is to provide a fiber-reinforced thermoplastic resin sheet which can be manufactured into a molded body exhibiting excellent appearance quality as well as exhibits both high moldability and strength and a manufacturing method of such a fiber-reinforced thermoplastic resin sheet. The present invention relates to a fiber-reinforced thermoplastic resin sheet which is a random laminated body of a tape-shaped unidirectional prepreg and contains spread reinforcement fibers and a polymer (a) and in which the polymer (a) is a polymer of at least a bisphenol A type epoxy compound represented by Formula (1): where n is an integer of 1 to 4 and a bisphenol compound selected from the group consisting of bisphenol A, bisphenol F, bisphenol S, bisphenol B, bisphenol E, and bisphenol P.
