Disclosed is a conductive particle capable of reducing connection resistance when electrodes including a titanium electrode are electrically connected. A conductive particle according to the present invention is used for electrical connection of a titanium electrode, has a conductive portion at least on the surface, the conductive portion has a plurality of protrusions on the surface, and is electrically conductive. The compressive elastic modulus when compressive particle 1 is compressed by 10% is 9000 N / mm 2 or more, the compressive elastic modulus when compressed by 20% is 8000 N / mm 2 or more, and the compressive elastic modulus when compressed by 30% Is 7000 N / mm 2 or more, and the compression recovery rate of the conductive particles 1 is 60% or more and 90% or less.
