PURPOSE:To obtain an information recording medium having excellent S/N, etc. by providing a recording layer on one of a pair of substrates, using a resin curable by UV rays which affects the recording layer for said substrate, using a high-power adheisve resin curable by UV rays for the other substrate and sealing the substrates in such a manner that a space remains therebetween. CONSTITUTION:The recording layer 3 is provided to one of a pair of the disk- shaped substrates 1, 1. The resin 7 curable by UV rays such as urathane acrylic resin which does not affect adversely the layer 3 is used to the inside and outside circumferential part of the substrate 1 and an adhesive agent 8 such as tetrahydrofulfuryl acrylate curable by UV rays having high adhesive power is used to the inside and outside circumferences of the other substrate 1. These substrates are integrally sealed by providing the space 6 therebetween via spacers 4, 5 provided respectively to the inside and outside circumferences. The high adhesive power is thus provided to the recording medium and the need for the long-term use of member fixing jigs during curing is eliminated; in addition, the generation of the deformation, etc. of the substrates is obviated. The information recording medium having the excellent reflectivity, S/N, etc. is obtd.
