<p>A coaxial connector that can be connected to a receptacle in mechanically and electrically stable conditions and is low in height, and a communication device. A coaxial connector in which two longitudinal slits (31) are arranged at the lower section of a tubular section (24) that is in contact with an external conductor of a receptacle, the slits being in the direction parallel to the direction of insertion in a receptacle. A longitudinal cutout (33) is formed in the lower part of the tubular section (24), the cutout starting at the lower end of the tubular section (24) and being parallel to the direction of insertion in the receptacle. Further, a lateral cutout (24b) is provided from the longitudinal cutout (33) in the direction orthogonal to the direction of insertion in the receptacle. The lateral cutout (24b) is provided left-right symmetric relative to the longitudinal cutout (33).</p>
