ABSTRACT:
A tape cassette having a tape guide for contacting with a magnetic tape provided as a tape coil within a main cassette body, and guiding the running of the magnetic tape, is disclosed. The tape guide for guiding the magnetic tape is molded with a lower cassette half integrally from an ultra high molecular resin having a molecular weight ranging from 500,000 to 1,000,000 for simplifying the assembling process and reducing production costs as well as preventing adverse effects of deviation from true verticality of the tape guide on the magnetic tape during recording/reproduction or fast feed/rewind to assure stable tape running.
