With respect to fiber-reinforced plastics in which a base member is at least partially reinforced with a continuous fiber-reinforced resin member, there is provided a fiber-reinforced plastic in which the continuous fibers forming the continuous fiber-reinforced resin member do not bend, and, further, the base member and the continuous fiber-reinforced resin member are made to favorably adhere to each other, as well as a method of producing same. Provided is a fiber-reinforced plastic in which at least a portion of the base member is laminated with, as a reinforcement member, the continuous fiber-reinforced resin member. An adhesion layer comprising a thermoplastic resin is present between the base member and the reinforcement member, the adhesion layer making the two adhere to each other. With respect to the thermoplastic resin of the reinforcement member, assuming Tg1 denotes its glass transition point if it is an amorphous plastic, or Tm1 its melting point if it is a crystalline plastic, and with respect to the thermoplastic resin of the adhesion layer, assuming Tg2 denotes its glass transition point if it is an amorphous plastic, or Tm2 its melting point if it is a crystalline plastic, then Tg1>Tg2 or Tm2, or Tm1>Tg2 or Tm2.
