摘要	PROBLEM TO BE SOLVED: To obtain surface-modified carbon fiber with excellent adhesivity to matrix resins, useful in e.g. composite materials by electrolytic treatment of a specific carbon fiber as anode using a specified electrolyte. SOLUTION: This surface-modified carbon fiber is obtained by electrolytic treatment of carbon fiber in elastic modulus as anode using an inorganic alkaline electrolyte of >=pH 7 or an electrolyte prepared by adding an aromatic compound (so as to be 0.1-10 wt.% a in concentration) such as a compound of formula I, II or Ill (X is an alkyl, an alkoxy, carboxyl, vinyl or a C=C-bearing functional group; (n) and (m) are each 1-4) having one or more hydroxyl or amino groups to an aqueous solution of ammonium salt of >=pH 7.
