PROBLEM TO BE SOLVED: To provide a composite sheet which is inexpensive, reduced in the coefficient of linear expansion, has good surface smoothness and can be suitably utilized as an optical sheet, a plastic substrate for a display element or a substrate for an active matrix display element. SOLUTION: In the manufacturing method of the composite sheet comprising a thermosetting resin and glass cloth, a prepreg obtained by coating the glass cloth with the thermosetting resin is rolled once or a plurality of times by a calender, of which the roll surface is constituted of a metal having a fluoroplastic polymer uniformly dispersed therein, at the time of crosslinking and molding the prepreg to obtain the composite sheet excellent in smoothness.
