Abstract
Provided are an electro-conductive composition improved on its wettability and handled with ease and an electronic equipment using the same. The electro-conductive composition comprises: 28 to 45 wt % metallic particles X to form an alloy with a solder at a soldering temperature and to increase a melting point of the solder to a temperature higher than the soldering temperature; 30 to 60 wt % metallic particles Y hard to form an alloy with the solder at the soldering temperature, wherein the sum of contents of the metallic particles X and Y is in the range of 75 to 93 wt %; and the rest of a resin.
