An optical, transparent, highly pressure-sensitive adhesive material is provided in which selectivity for the separation boundary between each surface of the transparent pressure-sensitive adhesive material and the release sheet is stably obtained when the adhesive material is applied, and in which selectivity for the separation boundary of each surface of the transparent pressure-sensitive adhesive material is stably and easily obtained when the adhesive material is reworked, i.e., reapplied. Furthermore, the adhesive material has excellent adhesion stability after application. Also provided are an optical transparent pressure-sensitive adhesive laminate and a process for producing the laminate. The optical transparent pressure-sensitive adhesive material has a pressure-sensitive adhesive surface (a) and a pressure-sensitive adhesive surface (b) which differ in pressure-sensitive adhesive property, and is formed from an addition reaction type silicone gel. The optical transparent pressure-sensitive adhesive material is characterized in that the tackiness (Ga) of the pressure-sensitive adhesive surface (a) and the tackiness (Gb) of the pressure-sensitive adhesive surface (b) have the relationship Ga
