[Problem] To provide a method for modifying the surface of a composite material, whereby it becomes possible to improve the bonding of the composite material to a bonding agent while preventing the composite material from being deformed. [Solution] A bonding position which is positioned on the surface of a composite material comprising a reinforcing base member impregnated with a resin and onto which a bonding agent is to be applied is irradiated with laser to cause the reinforcing base member to be exposed and fluffed. 提供能够抑制复合材料的变形且提高复合材料对粘接剂的粘接性的复合材料的表面改性方法。通过对在增强基材中浸渗有树脂的复合材料的表面中要涂布粘接剂的粘接位置照射激光，从而使前述增强基材露出，使前述增强基材起毛。
