Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a heat-resistant sheet excellent in specific water absorptivity and shape stability, mechanical performances, or the like, at high temperatures. SOLUTION: This sheet comprises 95-75 wt.% of melt anisotropic polyester fibers (component A) and 5-25 wt.% of heat-resistant fibers (component B) manifesting a negative coefficient of linear expansion at 25-150 deg.C and having >=300 deg.C decomposition temperature and >=550 g/d tensile modulus of elasticity at 150 deg.C, e.g. p aramid fibers.
