Abstract: A tacky gel sheet having adhesive uses, comprising an organogel having tackiness before curing and having adhesiveness after curing to an adherend, in which the organogel (i) comprises a polymer matrix including a (meth)acrylate-based resin, a plasticizing component having curability, and a curing agent having reactivity with the plasticizing component, and (ii) (1) has a viscoelastic property expressed by a storage modulus of 1.0×103 to 5.0×104 Pa and a loss factor of 0.01 to 2 (at a frequency of 0.01 Hz and at 23° C.), and a storage modulus of 1.0×104 to 1.0×107 Pa and a loss factor of 0.01 to 2 (at a frequency of 100 Hz and at 23° C.) and (2) has a tacking force of 0.01 to 0.15 N/mm2 (at 23° C.) before curing, a tensile shear adhesion strength of 3 N/mm2 or more (at 23° C.) and a tensile adhesion strength of 1 N/mm2 or more (at 23° C.) after curing.
