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 polishing region on a surface of the carbon fiber composite material molded in the molding step, with an abrasive that has a predetermined hardness;
• a bonding step of bonding, through an adhesive, another member to a part of the polishing region polished by the polishing step, wherein
• the molding step forms, in a top layer, a non-conductive layer for protecting the carbon fiber composite material from the abrasive.

A structure formed with a carbon fiber composite material that is a resin material reinforced with carbon fibers and polished with an abrasive with a predetermined hardness, the structure comprising:

• a polishing layer that is formed in a top layer and has hardness lower than the predetermined hardness;
• a surface protective layer that is lower than the polishing layer, protects the carbon fiber composite material from the abrasive, and has hardness higher than the predetermined hardness;
• and
• a carbon fiber layer composed of the cured resin material containing the carbon fibers therein.
