Abstract An electro-conductive ceramic guide made by the use of a mixture of a metallic titanium and metallic titanium dioxide prepared at a mol ratio of 1 : 0.06 - 1.22, molding this mixture into an element of desired shape, and sintering the shaped element at 1,200* - 1,450* C in vacuum or in an inert atmosphere to cause the crystal particles of the element to have a face-centered cubic crystal structure. The resulting element is mounted at a site where it is brought into a running tape or like article. This guide is of a very small friction coefficient and imparts a stable low tension to the running tape, and has a high electroconductivity thereby being capable of removing static charge of the tape and is highly suitable for guiding video tapes and computer tapes.
