Abstract
A fastening structure is fastened to an object. The fastening structure includes a carbon fiber-reinforced resin, a metal collar and a fastener. The outer circumference of a metal collar has a tapered portion, which is inclined with respect to the central axis of the collar. The inner circumferential surface of a through hole in a carbon fiber-reinforced resin ('CFRP') material has an abutting portion that contacts the tapered portion of the collar via an electrically insulating adhesive. The tilt angle of the tapered portion of the collar and of the abutting portion of the CFRP material are the same as the angle at which the displacement of the CFRP material in a direction perpendicular to the surface of the abutting portion due to thermal deformation resulting from temperature changes is balanced with the displacement of the collar in a direction perpendicular to the surface of the tapered portion.
