Zusammenfassung:	The present invention relates to a polyester resin foam sheet and a method for manufacturing the same, and by including regions having different thicknesses and cell sizes in the width direction of a foam sheet, it is possible to increase processability for the manufactured foam sheet and reduce process variables. The foam sheet includes a region having a thickness of D1 and a region having a thickness of D2 based on a cross-section in the width direction (TD) of the foam sheet, and a ratio of D1 to D2 is in the range of 5 : 1 to 1.2 : 1. 본 발명은 따른 폴리에스테르 수지 발포시트 및 이의 제조방법에 관한 것으로, 발포시트의 폭 방향 두께 및 셀 사이즈가 상이한 영역들을 포함함으로써, 제조된 발포시트에 대한 가공성을 높이고 공정 변수를 줄일 수 있다.
