Abstract: In this proceeding, a summary is given of the newly published or preliminary experimental results on charm studies at Belle experiment at KEKB. It mainly includes three parts: ① D0-D0 mixing and CP violation. Some decay channels give the new measurement results with better precision; ② search for D0 rare decay with most restrictive upper limit; ③ some new results for charmed baryon studies, such as doubly charmed baryons, charmed strange baryons and so on.
