Conductive particles, a method of manufacturing a conductive particle, an anisotropic conductive material and a connection structure

It can inhibit corrosion of the electrodes, to provide conductive particles can increase the conductivity reliability between the electrodes, and a connection structure using the conductive particles. Conductive particles (1) has a conductive layer (3) at least on the outer surface (1a). The 1g liquid conductive particles (1) were added to ion-exchanged water 10mL of, when heated at 121 ° C. 24 hours in a sealed under the concentration of organic acids in the aqueous phase in the liquid after heating the conductive particles it is equal to or less than 300μg / g in terms. Connection structure (21) includes an electrode first connection object member having a (22a) (22), and the electrode second connection object member (23) having a (23a), said first, second connection comprising connecting portion connecting the target member (22, 23) and (24). Connecting portion (24) is formed by an anisotropic conductive material containing or being formed, or the conductive particles (1) and the binder resin of a conductive particle (1). The electrode (22a) and the electrode (23a), are electrically connected by the conductive particles (1). .FIELD 1
