The electrically conductive connection sheet 1 of this invention is comprised by the laminated body provided with the resin composition layers 11 and 13 and the metal layer 12, and the resin composition layers 11 and 13 satisfy | filling the following requirement A. will be. When applied to the formation of the connection part which electrically connects between terminals using the electrically conductive connection sheet 1 of such a structure, a heat-melted metal material is selectively aggregated between terminals, and a connection part is formed and the resin is surrounded by The sealing layer comprised by a component can be formed. As a result, since the periphery of a connection part can be coat | covered with a resin component, a connection part is fixed. In addition, since insulation between adjacent terminals is ensured by the sealing layer, it is possible to reliably prevent leakage current from occurring between adjacent terminals. Requirement A: According to the resin-based flux test method specified in JIS Z 3197, in the state of arranging at least a part of the metal ball made of a low melting point metal material in the resin composition layers 11 and 13, the metal ball When it heats more than melting temperature of, and the wet diffusion rate of the said metal ball is measured after that, the wet diffusion rate becomes 37% or more. |
