Abstract: PURPOSE:To enable reduction of the occurrence of stress concentration by which exfoliation is caused, by a method wherein an adhesion region, where the action component of a load is present is inequally formed in a direction extending along a contact surface between a load receiving part and a parent material. CONSTITUTION:In an adhesion region where the action component of a load F is present in a direction extending along a contact surface between a load receiving part 1 and a parent material 2, a distance lx between the load receiv ing part 1 and the parent part 2 in each position on the contact surface is inequally formed according to stress characteristics of an adhesive 3.
