Title: ELECTROMAGNETIC WAVE ABSORBING SHEET
Abstract:
The present invention achieves an easily handleable electromagnetic interference type electromagnetic wave absorbing sheet which is capable of absorbing electromagnetic waves in a desired frequency range well, while having high flexibility and light transmitting properties. According to the present invention, an electromagnetic wave absorbing sheet having flexibility and light transmitting properties is formed by laminating a resistive film 1, a dielectric layer 2 and an electromagnetic shielding layer 3, all of which have light transmitting properties. The resistive film is formed from a conductive organic polymer; and the aperture ratio of the electromagnetic shielding layer is from 35% to 85% (inclusive).
