A receptacle for coaxial connector includes an outer conductor having a tubular portion, a central conductor having a central-conductor contact portion extending in an axis direction in an internal space of the tubular portion, and an insulator holding the outer conductor and the central conductor in an insulating state. An overhanging region made of the outer conductor and the insulator overhangs in a direction perpendicular to the tubular portion of the outer conductor. In this overhanging region, the outer conductor includes outer-conductor overhanging portions, and the insulator includes an insulator overhanging portion. The outer-conductor overhanging portions and the insulator overhanging portion have substantially the same thickness.
