A tape guide member is disclosed which is prepared from a mixture of engineering plastics, carbon fibers, and an ester of a higher fatty acid, and a polyhydric alcohol. The members may be suitably used as tape guides of video tape cassettes, audio tape cassettes, and memory tape cassettes. Use of the present tape guide results in a lower degree of dropouts after repeated tape running.
