A fiber-reinforced resin substrate is described in which a plurality of resins having differing properties are strongly composited, wherein the fiber-reinforced resin substrate is obtained by impregnating a thermoplastic resin (A) and a thermoplastic resin (B) into continuous reinforcement fibers, wherein a thermoplastic resin (A) layer, which comprises the thermoplastic resin (A) and is exposed at one surface, and a thermoplastic resin (B) layer, which comprises the thermoplastic resin (B) and is exposed at the other surface, form a boundary region, where at least some of the continuous reinforcement fibers exist in a manner spanning across the boundary region and both the thermoplastic resin (A) and the thermoplastic resin (B) are crystalline resins having a melting point of not less than 200 C.

An object is to provide a fiber-reinforced resin that can be welded to another member via a thermoplastic resin and that is less likely to be damaged even when welded at a high temperature, wherein the fiber-reinforced resin includes a reinforcing fiber and has a cured epoxy resin region and a thermoplastic resin region disposed at the surface wherein aromatic rings account for 50% or more and 90% or less of the cured epoxy resin present in the cured epoxy resin region.
