An electromagnetic wave shielding sheet according to the disclosure is configured by a protection layer, a metal layer, and a conductive adhesive layer. The metal layer has a plurality of openings, and an aperture ratio of the opening is 0.1%-20%. In addition, a tensile breaking strength of the electromagnetic wave shielding sheet is 10 N/20 mm-80 N/20 mm.

An object of the present invention is to provide a thermal conductivity-giving material capable of giving substantially the same level of a thermal conductivity as that of the conventional material by using a smaller amount thereof than that conventionally used or giving a higher thermal conductivity than that of the conventional material by using substantially the same amount thereof as that conventionally used. The aforementioned problem can be solved by an easily deformable aggregate (D) comprising 100 pts&#xb7;mass of thermally conductive particles (A) having an average primary particle diameter of 0.1 to 10 &#x3bc;m, and 0.1 to 30 pts&#xb7;mass of an organic binding agent (B), in which the easily deformable aggregate (D) has an average particle diameter of 2 to 100 &#x3bc;m, and an average compressive force required for a 10% compressive deformation rate is 5 mN or lower.
