    Abstract: A coaxial connector includes internal and external terminals, and an insulation member disposed between the terminals. The external terminal includes a holding portion that holds coaxial cables, and crimping portions. A crimping portion outermost in an arrangement direction of the cables is formed from a plate member bent to follow an outer circumference of the cable, and includes a connection portion connectable with the holding portion between both end portions in the arrangement direction. An inner hook extends inward in the arrangement direction from a point of intersection between the connection portion connectable with the holding portion and a virtual straight line orthogonal to the arrangement direction and passing a center of the cable, in a cross-sectional view orthogonal to a longitudinal direction of the cable. An outer hook extends outward in the arrangement direction from the point of intersection. The inner hook is shorter than the outer hook.
