The present invention relates to an electrical contact material having a surface layer made of a noble metal or an alloy having the noble metal as its main component, a method for manufacturing the same and an electrical contact using the same. Recently, electrical contact materials having excellent abrasion resistance are used for sliding electrical contacts such as a connector terminal of an automobile harness, a contact switch mounted in a cellular phone and terminals of a memory card. Although there have been known ones having an organic coating film composed of either aliphatic amine or mercaptan or a mixture of the both provided on the electrical contact material described above as the electrical contact materials having excellent abrasion resistance, they have had problems that even though they are effective with a low load of 0.5 N or below, abrasion accelerates when the load exceeds 0.5 N and sliding characteristics drop under a high-temperature environment. The invention solves the abovementioned problems by providing an organic coating film formed of an organic compound containing aliphatic amine on the electrical contact material.
