To provide a lightweight fiber-reinforced composite for a wind turbine component, allowing high air resistance or low air resistance to be added to a surface, and/or allowing an emboss pattern for reducing wind noise to be easily formed, furthermore, permitting the emboss pattern to be produced at low cost, and further, having excellent surface design.
The fiber-reinforced composite is formed by stacking a prepreg 20 onto an embossed surface of an embossed mold release paper 10 and performing auto-clave molding to transfer and form an emboss pattern of the emboss on the surface. The embossed mold release paper 10 is formed by laminating a first mold release layer 17A, a first resin layer 15A, a first wood filling layer 13A, a support member 11, a second wood filling layer 13B, and a second resin layer 15B. An emboss pattern is formed on the side facing the first mold release layer 17A of the first resin layer 15A.
