To provide a combination structure of a rigid body and an elastic body, which allows the rigid body to be easily rapidly detached from the elastic body, and combines the advantages of both materials.

The combination structure of a rigid body and an elastic body is constructed from a rigid body 10, an elastic body 20, and a connection member 50. The rigid body 10 is comprised of a material such as glass, a pottery, and a porcelain, and provided with an open portion 11 and an opening 12. The elastic body 20 is comprised of a material such as plastic and the like, and provided with a coupling portion 21 and a through hole 22. A connection member 50 is provided with a connection portion 51, and caused to abut the bottom portion of the open portion 11. A structure in which the connection portion 51 and the coupling portion 21 are connected to each other enables the rigid body 10 having advantages such as resistance to deformation and excellence in texture to be easily rapidly detached from the elastic body 20 having advantages such as ease of molding and convenience of assembly.
