In this paper, we study a certain extension of Nori’s fundamental group in the case where a base field is of characteristic 0 and give structure theorems about it. As a result for a smooth projective curve with genusg>1, we prove that Nori’s fundamental group acts faithfully on the category of unipotent bundles on the universal covering. In the case wheng= 1, we give a more finer result.
