A tube joint comprises a joint body which is provided with an attachment/detachment mechanism for attaching/detaching a fluid tube and which is formed of a resin material, and a bellows section which has annular projections and annular recesses alternately formed to be continuous in an axial direction and which disperses external force (impact force) applied to an outer surface of the joint body to avoid any concentration of stress.
