Abstract
A guide post for magnetic tapes manufactured by injection molding of a composite material prepared by mixing a thermoplastic resin used as a basic ingredient with an electrically conductive carbon black and a spherical silicon resin. This guide post can exhibit characteristics equivalent to those of the metal guide post owing to the function of the electrically conductive carbon black and the spherical silicon resin. The composite material can further contain a solid lubricant mixed therewith.
