Abstract
There is provided a technique for producing an oxide-dispersion-strengthened platinum material excellent in high-temperature creep properties and having high elongation properties. The material of the present invention has a structure comprising concentrated layers in which an additive metal for oxide-dispersion strengthening or a metal oxide thereof is concentrated and platinum layers essentially consisting of platinum in which the additive metal or the metal oxide thereof is dilute, the concentrated layers and the platinum layers being alternately laminated in six pairs or more. In addition, the outermost surface of the material is preferably the platinum layer or the concentrated layer.
