PURPOSE:To prevent the peeling of adhesive surfaces and the deterioration of mechanical characteristics by using a material having <=10% thermal shrinkage by heating as a base film material for a double-coated tape. CONSTITUTION:This recording medium has a substrate 1 consisting of a resin (thermoplastic resin, such as polycarbonate resin, thermosetting resin, such as epoxy resin, UV curing resin or the like) or glass, the base film 2 which is the double coated tape, tacky adhesive agent layers 3 of the double coated tape, and thin-film layers 4 contg. recording films. The base film 2 is formed of a material which is thermally shrunk by <=10% only by the heating in an at least 60 to 120 deg.C range. The recording medium having excellent heat resistance is obtd. without generating the peeling at the time of a high temp. and a change in the mechanical characteristics. |
