PROBLEM TO BE SOLVED: To reduce operating man-hours and manufacture high-quality FRP by laminating a base material layer and a smoothed layer in advance into an integrally joined piece. SOLUTION: The laminated glass fiber product is integrally formed of a base material layer consisting of a chopped strand mat of glass fibers, a roving cloth or a joined body thereof and a smoothed layer comprising glass fiber paper or a non-woven fabric, laminated and integrally joined in one piece. Further, the laminated glass fiber product is manufactured by superposing glass paper or a glass non-woven fabric which becomes the smoothed layer over the chopped strand mat, the roving cloth or the joined body thereof which becomes the base material layer and heating this laminate under pressure and further, integrally joining the glass paper or the glass non-woven fabric with a resin used as an integrating agent, as an adhesive. Thus it is possible to manufacture an FRP product which shows high planar smoothness, superb mechanical properties and high quality at a high production rate.
