To provide an information recording medium and an IC card, having excellent durability in terms of impact, point pressure, bending performance, twist performance, etc.

In the information recording medium disposed with an IC module 2 including an IC chip 2a, a reinforcing plate 2d adjacent to the IC chip 2a, and an antenna 2b connected to the IC chip 2a, in which the IC module 2 is provided via adhesive agent, between the IC chip 2a and the reinforcing plate 2d, there disposed is an adhesive layer 2e of which 180-degree peeling-off adhesion force measured in conformity to JIS Z0237 is in the range of 0.1-10 N/25 mm. The tensile modulus of elasticity of the adhesive layer 2e measured in conformity to ASTM D638 is from 0.1 to 20.0 kg/mm2. At least in one portion or the entire periphery of the IC chip 2a, the reinforcing plate 2d and the adhesive layer are coated with a composition 30 having a dilatancy characteristic. The composition 30 having the dilatancy characteristic is covered with a separation layer 31.
