We will report results of GMVA and VSOP observation of M 87.
In order to investigate the innermost region of the M 87, we conducted GMVA observation in 2014.
We revealed double ridge structure as is observed by VLBI at low frequency observations.
The measured streamline is reasonably agreed with the previous observations at low frequency.
We will discuss the origin of the jet based on this new derived streamline.
