    摘要: An electromagnetic wave shielding material includes a metal layer for ground connection provided as an outermost layer of a laminate; wherein only one surface of the metal layer for ground connection is laminated on the insulating layer via the adhesive layer, and assuming d1 is a thickness and ε1 is a Young's modulus of the adhesive layer on the one surface, d2 is a thickness and ε2 is a Young's modulus of the metal layer for ground connection, and ε3 is a composite Young's modulus of the adhesive layer on the one surface and the metal layer for ground connection, the following relational expression is satisfied: ε3/ε2>0.60; in which, ε3=ε1 (d1/(d1+d2))+ε2 (d2 (d1+d2)).
