A laminated product according to the present invention has a fiber reinforced resin layer, an elastic layer laminated on one surface of the fiber reinforced resin layer, and a surface protection layer laminated on a surface of the elastic layer for protecting the surface of the elastic layer. The fiber reinforced resin layer includes at least two prepreg sheets, each of which is formed by impregnating a thermoplastic resin into continuous reinforcing fibers arrayed in one direction such that the volume ratio of the continuous reinforcing fibers is in the range of 40 to 80%. The prepreg sheets are laminated so as to the array directions of the continuous reinforcing fibers at right angles.
