Abstract
A magnetic tape cassette of reduced thickness which can be manufactured with high productivity. The cassette includes a lid having a pocket and a body, the latter having rotation-preventing projections formed integrally therewith, which are pivotally coupled to each other so as to open and close in the manner of a book. Recesses are provided in the lid and body in which the thick portion of the cassette is accommodated. Projections are provided on the bottom of the recess of at least the body of the case, which projections extend up from the bottom of the recess in the direction of thickness of the case. At least the tops of the projections are aventurine surfaces.
