PROBLEM TO BE SOLVED: To provide a cover member for a curing material which can press the curing material by only putting on the periphery or the like of the curing material such as a curing sheet and which can be repeatedly used many times. SOLUTION: A tabular main body 10 made of flexible synthetic resin by the extrusion molding, in which a number of projections with an appropriate height are protruded on the whole face of one side, is doubly folded to form a rectangle. The folded end edges are fixedly superposed and flat spaces are formed by the projections. In this way, a main body 14 of the member provided with an indication 15 on the surface is constituted. An adhesive tape 17 is stuck on one opening of the main body 14 to close the opening. A filler such as sand is charged in the flat space through the other opening in order to increase the entire weight. The other opening is closed by the adhesive tape 17 attached thereto.
