Abstract
An electrical resistance element with electrode portions comprising a thin resistance wire of a heat resistant material, such as molybdenum disilicide, MoSi.sub.2, which resistance wire has at least one end electrode of aluminium, having a much greater cross-sectional area than that of the resistance wire, wherein the end portion of the resistance wire is fused into the end portion of the respective electrode portion. Also disclosed is a method of connecting an electrode portion to one end of the resistance wire in an electrical resistance element by placing the end portion of the electrode within a surrounding sleeve, heating the sleeve with the electrode end therein to cause the outermost end portion of the electrode end to form a melt, introducing the resistance wire end into the melt and permitting the melt to solidify and finally removing the electrode and resistance wire connected thereto from the sleeve.
