The present invention provides a resin particle, which can effectively inhibit aggregation, and when conductive particles with conductive parts formed on the surface are used to electrically connect between electrodes, it can effectively improve the adhesion with the conductive parts, thereby being effective Ground to reduce the connection resistance. Regarding the resin particles of the present invention, for the outer surface of the resin particles, when the negative ion mass spectrum is obtained by time-of-flight secondary ion mass spectrometry, the ratio of the intensity of OH- ions to the sum of the intensities of all negative ions is 2.0×10 -2 the above. |
