Abstract

An electro-conductive pressure-sensitive adhesive tape comprises a pressure-sensitive adhesive layer containing a resin component and an electro-conductive particle. The electro-conductive particle has at least one peak top existing in a particle size range from about 15 μm or more to about 50 μm or less and at least one further peak top existing in a particle size range from about 1 μm or more to about 12 μm or less in a particle size distribution curve thereof. The electro-conductive particle is contained in the pressure-sensitive adhesive layer in an amount of 40 mass % or more but 80 mass % or less, and has a true density in a level of larger than zero but smaller than 8 g/cm.
