A process for producing a superconducting wire rod having a high-resistance layer on the external side of a superconductor, in which a homogeneous high-resistance layer can be easily formed; a relevant superconducting wire rod; and a relevant superconducting equipment. A superconductor material is coated with a first silver-containing metal to thereby obtain a silver sheathed member. This sheathed member is coated with a nonsilver metal in which no silver is contained. In the member coated with the nonsilver metal, at least portion of the first silver-containing metal and the nonsilver metal are converted to an intermetallic compound. The metal in the form of the intermetallic compound is oxidized to thereby obtain a high-resistance layer. The member provided with the high-resistance layer is subjected to thermal treatment, thereby accomplishing conversion of the above material to a superconductor.
