[Problem] An arcing horn, or the like, for guiding an arc occurring when opening/closing an electric contact thereby preventing erosion of the contact point or a support material, or, a protruding portion of the support material provided at an extremity portion of the contact point in the direction in which the arc is driven thereby rendering the contact point difficult to melt, are known ways in prior art to prevent detachment and erosion. However, as these methods are only realizable if sufficient space can be secured for an arc-extinguishing chamber, or if sufficient dimensions of the support material can be secured, these methods are not necessarily adoptable if a device is to be reduced in size. [Solution] The present invention is characterized in that an electric contact point and a contact element having improved resistance to erosion are achieved by a reduction in the amount of erosion at the electric contact point, comprising pasting onto the surface of a pure silver layer on the back side of a contact point where detachment and erosion readily progress, a copper or a copper alloy having excellent electric conductivity, heat conductivity and mechanical strength as a functional layer, thereby conferring to the functional layer a function of transmitting to a support material the heat generated when opening/closing the electric contact, a function of shortening the duration of chattering, and a function of preventing detachment and erosion, or the like, by maintaining the strength of the bond with the support material.
