ELECTRICALLY CONDUCTIVE SHEET AND PROCESS FOR PRODUCING SAME, AND ELECTRONIC COMPONENT

摘要

Provided are: an electrically conductive sheet having good processability, whereby it becomes possible to minimize the leaching of an electrically conductive layer in a hot-pressing step for adhering the electrically conductive sheet onto an object of interest, such as a printed wiring board; a process for producing the electrically conductive sheet; and others. This electrically conductive sheet involves an electrically conductive layer comprising at least a heat-curable resin (A) and dendritic electrically conductive microparticles (B). The thickness of the electrically conductive layer fulfills the following requirement (i) and/or (ii): (i) the thickness of the electrically conductive layer becomes 30-95 after being hot-pressed under the conditions of 150ºC, 2 MPa and 30 minutes when the thickness of the electrically conductive layer before the hot-pressing is defined as 100; and (ii) the average particle diameter (D90) of the dendritic electrically conductive microparticles (B) becomes 0.5-3 times the thickness of the electrically conductive layer. The dendritic electrically conductive microparticles (B) have an average particle diameter (D50) of 3-50 µm inclusive and are contained in an amount of 50-90 wt% inclusive in the electrically conductive layer.
