Present status of a pressurized superfluid helium cooling and its related high field superconducting magnet is reviewed. The research and development of high field superconducting magnets employing multifilamentary superconducting wires have been performed so far. NbTi alloy and Nb3Sn compound superconducting wires have indicated their own properties enough to be high field superconductors and have been practically applied for high field superconducting magnets. In order to construct high field superconducting magnets, the optimization of a coil structure which enables us to stand a huge electromagnetic force and effectively to generate a magnetic field is needed. It is desired that the pressurized superfluid helium cooling will contribute to the optimization of superconducting magnets and will improve their performances in high fields.
