To prevent the missing of pattern, dropping of pattern due to rubbing, the deterioration of bonding force, make it harmless to human body and improve workability by a method wherein an adhesive layer is formed of a hot-melt type ionized radiation curing resin.

In an inorganic decorative panel 1, in which an inorganic substrate 2, an adhesive layer 3, a thermoplastic resin layer 4, a printing layer 5 and a protecting layer 6 are laminated, the adhesive layer 3 is formed of a hot-melt type ionized radiation curing resin. The ionized radiation or ultraviolet ray curing resin is preferable to be the copolymerized product of the trunk polymer of ionized radiation curing resin and a photo-initiated polymerization initiator since the contamination of a human body or the stimulation of skin due to the eluation of the photo-initiating polymerization initiating agent can be avoided. The forming method of the adhesive layer 3 is a direct coating method, wherein a coating composition is applied directly on the surface of the inorganic substrate 2, a transfer coating method, wherein the adhesive layer is formed on the surface of a separable substrate previously and, thereafter, the adhesive layer is transferred on the surface of the inorganic substrate 2, or the like.
