Provided is an adhesive member whose adhesive force has relatively strong directional dependency. Specifically, provided is an adhesive member, which is configured to adhere to an adherend through an intersurface force, wherein when a strain energy release rate is defined as G1c and G2c and an adhesive energy is defined as Δγ1c and Δγ2c respectively, the Δγ1c and the Δγ2c differ from each other so that G1c/Δγ1c≠G2c/Δγ2c is satisfied.
