Abstract: A connection terminal that includes an alloy containing layer, in which grains of an alloy part made of an alloy mainly containing tin and palladium are present in a tin part made of pure tin or an alloy having a higher tin ratio than the alloy part, wherein: both the alloy part and the tin part are exposed on an outermost surface of a contact point to be electrically brought into contact with another conductive member, and a number of the grains having an area circle equivalent diameter of 1.0 ?m or larger is 30% or higher to a total number of the grains in a grain size distribution of the grains of the alloy part on the outermost surface of the contact point.
