Abstract
An anisotropically conductive sheet of the invention formed by containing conductive particles exhibiting magnetism in a sheet base composed of an elastic polymeric substance in a state dispersed in a plane direction thereof and oriented so as to align in a thickness-wise direction thereof. A thickness of the sheet is 10 to 100 μm, a number average particle diameter of the conductive particles exhibiting magnetism is 5 to 50 μm, a ratio W1/D of the thickness W1 to the number average particle diameter D of the conductive particles exhibiting magnetism is 1.1 to 10, a content of the conductive particles exhibiting magnetism is 10 to 40% in terms of a weight fraction.
