Abstract: A connection structure includes: a first structure body and a second structure body which is detachably connected to the first structure body. The first structure body includes a first fitting portion, and the second structure body includes a second fitting portion which is detachably fitted with the first fitting portion. At least one of the first fitting portion or the second fitting portion is an anisotropic elastic structure body including a periodic structure and having an elasticity which differs depending on a direction. When a fitting direction in which the first fitting portion and the second fitting portion are fitted together is a first direction, and a direction which is orthogonal to the first direction is a second direction, the anisotropic elastic structure body has an elasticity which is greater in the second direction than in the first direction.
