A large current, such as a few ten kA, superconducting conductor is required for a fusion magnet. Superconducting strand having high critical current density and good drawing ability is therefore necessary. The development and technical issues of these superconductors are explained. In addition, instability particularly observed in a large current superconductor is introduced and studies about such instability are also described.
