The influence of oxygen partial pressure on the microstructure of Ag/Bi2223 tapes has been investigated in the condition of the powder-in-tube method. When oxygen partial pressure (PO<SUB>2</SUB>) was fixed at 7.8 kPa during the heat treatment at temperatures between 1102 and 1103 K, the highest value of critical current density (Jc) was achieved. However, Jc tended to decrease when the heat treatment temperature decreased to 1099 K under oxygen partial pressures between 3.0 and 7.8 kPa. When the volume fraction of 2223 phase increases and the alignment of plate-like 2223 grains becomes parallel each other, the Jc becomes higher.
