A coaxial cable includes an inner conductor including a central part and a conductive layer surrounding the central part, an insulator surrounding the inner conductor, and an outer conductor surrounding the insulator. The central part includes either a cavity or a portion made of resin material.

Provided are a receive cable and a medical image diagnostic system capable of reducing the burden on imaging staff. A receive cable includes: a coaxial cable; a tubular shield conductor accommodating the coaxial cable and having at least one non-conductive cutout portion at an intermediate portion in the axis direction; and a tubular conductor overlapping with the cutout portion and a part of each of two shield conductors located on both sides of the cutout portion, and is disposed with respect to the shield conductor via a gap portion in the diameter A direction of the shield conductor.
