ABSTRACT:
A magnetic tape cassette comprises an approximately rectangular bottom wall provided with an opening, into which a spindle is to be inserted, a side wall extending along the periphery of the bottom wall, and a structural part formed integrally with the bottom wall at a corner of the bottom wall and in proximity to the side wall. The magnetic tape cassette is of a thin-walled type, constituted of a resin, and integrally molded by feeding the resin from a position corresponding to the vicinity of a center point of the bottom wall into a mold. The bottom wall is provided with a flow path-like, thick-walled portion extending along a direction heading from the position in the bottom wall corresponding to the position, from which the resin is fed into the mold, approximately towards the structural part.
