Method of manufacturing structure, and structure

A method of manufacturing a structure including a carbon fiber composite material composed of a resin material reinforced with carbon fibers, the method comprising:

• a molding step of impregnating the carbon fibers with the resin material and curing the resin material for molding the carbon fiber composite material;
• a polishing step of polishing a predetermined region to be polished on a surface of the carbon fiber composite material molded in the molding step, with an abrasive that has a predetermined hardness;
• and
• a bonding step of bonding, through an adhesive, another member to a part of the predetermined region polished by the polishing step,
• wherein:
• in the molding step, a resin layer which is a deposition of the resin material which is soaked out by curing the resin material impregnated with the carbon fibers and a carbon fiber layer in which the carbon fibers are contained within the cured resin material are formed;
• the resin layer formed in the molding step is composed of a polishing layer formed in a top layer of the carbon fiber composite material that has a hardness which is lower than the predetermined hardness and a surface protective layer that is formed in lower than the polishing layer and that protects the carbon fiber layer from the abrasive, and has a hardness which is higher than the predetermined hardness;
• and
• in the polishing step, abrasion reaches a surface of the surface protective layer formed in lower than the polishing layer.
