The synchrotron radiation accelerator facility, so called light source accelerator, becomes widespread all over the world. Especially, the 3rd generation light source is applied to almost of the institute as a most useful machine for material structure science. As it spreads, the machine components is standardized to be able to respond to requirements of light performance from various beam line users. For this standardization, this report overviews how the superconducting technology has been treated as accelerator technology and future perspective of superconducting application in light source accelerator.
