The current status of adhesion technology, the concepts and guidelines for reliable bonding and design criteria are presented. It is important that the cohesive fracture rate is adjusted to 40%or more and the coefficient of variance of the bonding properties is adjusted to 0.10 or less. Durability is not a given property but a produced one. Combined joints are effective in the development of reliable systems.
