Imaging observation in the hard X-ray band of 10 - 100 keV is one of the important subjects in X-ray astronomy. Though SUMIT balloon-borne experiment, we have developed thin-foil-nested hard X-ray telescope employing depth-graded Pt/C multilayer (multilayer-supermirror). We have improved production process of the replica reflector and telescope optics compared with InFOCμS-2004 telescope. The new telescope was measured at synchrotron radiation facility, SPring-8. The image quality and throughtput were estimated to be 2.06 arcmin (half power diameter) and 85 % at 30 keV, respectively. These values were about 24 % and 30 % improvement compared to InFOC/μS-2004, respectively. Limiting factors of its performance are also investigated. Based on such an investigation we are now continuously developing hard X-ray telescope for SUMIT 2006 flight.
