	Hitachi is developing 9-cell superconducting cavities for ILC project in collaboration with KEK. We focus on electron beam welding (EBW) and plastic forming techniques. In 2010, Hitachi’s first 9-cell cavity without HOM couplers was completed successfully. Surface treatments and performance test of the cavity were carried out at KEK and the accelerating gradient reached 35.2 MV/m. We have undertaken the next 9-cell cavity with HOM couplers since January 2011. We will report the fabrication procedure and test result of first cavity and the current status of the next cavity.
