A resistor element includes a base substrate having first and second surfaces opposing each other and first and second end surfaces opposing each other and connecting the first and second surfaces. A first resistor layer is on the first surface of the base substrate. First and second terminals are respectively on the first and second end surfaces. A second resistor layer is on the first resistor layer, is connected to the first and second terminals, and includes a copper-manganese-tin (Cu&#x2014;Mn&#x2014;Sn)-based composition.

Resistor element and resistor element assembly

A chip resistor includes a board, first and second electrodes disposed on one surface of the board, and a resistor body electrically connecting the first and second electrodes to each other and including a copper-manganese-tin (Cu&#x2014;Mn&#x2014;Sn) alloy. In the Cu&#x2014;Mn&#x2014;Sn alloy, a percentage of Mn ranges from 11% to 20%, a percentage of Sn ranges from 2% to 8%, and a total percentage of Mn and Sn ranges from 13.5% to 22.5%.
