PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding sheet having a high shielding effect against electromagnetic waves and capable of suppressing secondary radiation causing a noise without being connected to GND. SOLUTION: The electromagnetic wave shielding sheet 30 is provided with a laminate film 14 on a base paper 12. The laminate film 14 has a laminate structure in which a first adhesive layer 16 having adhesive performance, a resistor film layer 18 and an insulating layer 20 are laminated. A specific resistance value of the insulating layer 20 is set at≥10<SP>6</SP>Ω/cm and a specific resistance value of the resistor film layer 18 is set at 10-300Ω. Thus, the secondary radiation can be reduced while maintaining a high shielding effect. Further, a magnetic layer 32 and a second adhesive layer 34 are provided between the base paper 12 and the laminate film 14, and thus, an absorbing effect can be further improved.
