An electromagnetic wave shielding sheet having a high shielding effect for electromagnetic waves and capable of suppressing secondary emission causing noises without using GND connection, in which the electromagnetic shielding sheet includes a laminate film on a paper substrate, the laminate film has a laminate structure where an adhesive layer having adhesion property, a resistor layer and an insulator are laminated, the resistivity of the insulator is set to about 106 Ω/cm or higher and the resistance value of the resistor layer is set to about 10Ω to 300Ω, so that secondary emission can be decreased while keeping a high shielding effect.
