Document Type and Number:
WIPO Patent Application WO/2024/049272
Kind Code:
A1
Abstract:
An electromagnetic wave shielding sheet is provided. The electromagnetic wave shielding sheet, according to one embodiment of the present invention, comprises: an electromagnetic wave shielding part, having a first surface and a second surface that face each other in the thickness direction and comprising a second conductive part of which one surface is the first surface, and a first conductive part of which one surface is the second surface and which has a three-dimensional network structure made of first metal-coated fibers having the metal layer thereof exposed to the outside; a cover member disposed on the first surface of the electromagnetic wave shielding part; and a conductive adhesive member having a portion of the entire volume in the thickness direction disposed on the second surface of the electromagnetic wave shielding part and the remaining portion disposed inside the second conductive part. The present invention according to the embodiment has excellent flexibility and thus attaches well to curved or stepped surfaces, can be implemented in a thin structure and thus is suitable for use in electronic devices which continue to decrease in thickness, and has an excellent vertical shielding performance notwithstanding the decrease in thickness and thus can minimize or prevent electromagnetic waves from leaking through side surfaces.
