PROBLEM TO BE SOLVED: To provide a conductive particle capable of making initial connection resistance low when a connection structure is obtained by electrically connecting electrodes by the conductive particle, and capable of maintaining connection resistance low even when the connection structure is exposed in a presence of acid. ! SOLUTION: The conductive particle 1 has a substrate particle 11, a first conductive layer 12 arranged on a surface of the substrate particle 11 and formed from silver or copper and a second conducive layer 13 arranged on an outside surface of the first conductive layer 12 and formed from nickel, the second conductive layer 13 contains nickel, boron, tungsten or molybdenum. !
