Abstract

PURPOSE:To prevent any deterioration of the conductivity of a porous thin film by making a base metal, which is contained in an alloy consisting of a noble metal and the base metal, to be deposited, rolling the former alloy into a foil, and dissolving and removing the deposits existing in the former foil so as to make a porous thin film. CONSTITUTION:80wt% Gold and 20wt% cobalt are molten in an atmosphere of argon so as to prepare an alloy. Thus prepared alloy is subjected to solution treatment at 1,000 deg.C for 24hr, and is subjected to ageing tretament at 500 deg.C for 8hr, thereby obtaining an ingot consisting of a mother gold phase, and cobalt deposited in the former gold phase. Thus obtained ingot, by taking advantage of the spreading property of gold, is rolled into a foil of around 1mu thickness. After that, the former foil is immersed in an acid so as to dissolve and remove the cobalt deposits existing in the foil, thereby a porous gold foil film being prepared. Thus prepared gold foil film is used for a supporting base used for the observatin of rhin films. By the means mentioned above, a supporting film with full conductivity can be obtained.
