Abstract
A hollow core body for signal transmission cable comprises an inner conductor that employs a compressed bunched conductor formed by bunching and compressing plural strands such that a cross-section of the compressed bunched conductor is substantially circular, and a hollow insulating core that includes an inner annular member, rib members, an outer annular member, and hollow members. Accordingly, as almost no recesses are produced on the circumferential surface of the compressed bunched conductor, weakening of the mechanical strength due to presence of recesses on the circumferential surface of the inner conductor can be suppressed.
