<p>An electroconductive particle including an electroconductive layer made of copper or a copper alloy, or silver or a silver alloy, and a surface layer made of nickel or a nickel alloy and formed on the electroconductive layer is used. By use of the electroconductive particle obtained such that a surface is coated with hard nickel, and an inner side of a nickel layer is copper or silver having low specific resistance, low resistance and high reliability can be obtained. An electroconductive particle having low resistance and high reliability, a circuit connecting material containing electroconductive particles, a mounting body using a circuit connecting material, and a method for manufacturing a mounting body are provided.</p> |
