Abstract
The metal foil resistor having a metal foil resistive element 20 composed of a metal foil whereupon a resistance circuit pattern is formed. The metal foil resistor comprises: a package 10 which contains the metal foil resistive element 20 in an electrically insulated state so that the resistive element can be expandable and contractible in a spreading direction of the metal foil; and a relay terminal 26 which is held in the package 10 in the electrically insulated state and is connected to an electrode 20a of the metal foil resistive element 20. A temperature coefficient of resistance can be reduced and stabilized. Control factors can be reduced to increase degrees in freedom in designing. Further, an external stress applied to a package is prevented from transmitting to the metal foil resistive element, and therefore the package can be easily attached to a discretionary heat sink.
