An oxide superconductor consisting of an oxide which comprises, as constituent metal elements, bismuth, lead, strontium, calcium and copper having a molar ratio of lead to bismuth of at least 0.2:1, and having an internal structure in which domains having a relatively high concentration of lead and no long-period structure are contained in domains having a relatively low concentration of lead and a long-period structure. This oxide superconductor has a storing pinning function and a high critical current density Jc even at a high temperature and a high magnetic field, can be produced by industrial methods, and is easily processed to form wires.
