PROBLEM TO BE SOLVED: To prepare a polyester resin sheet having an excellent autohesion property and embedding property and shows a heat resistance. SOLUTION: A polyester resin sheet has a glass transition temperature of 75 deg.C or higher and comprises from 15 to 85 pts.wt. copolymerized polyester wherein cyclohexanedimethanol substitutes for from 10 to 70 mol% ethylene glycol component of a polyethylene terepbthalate resin and from 15 to 85 pts.wt. resin having a glass transition temperature higher than that of the copolymerized polyester. |
