PROBLEM TO BE SOLVED: To provide a polybenzoxazole precursor which avoids the generation of ionic by-products in production, does not contain fluorine or a fluoroalkyl group and another halogen atom, and has good solubility in an organic solvent, and a polybenzoxazole obtained from the same. SOLUTION: The polybenzoxazole contains a repeating unit represented by general formula (I) (wherein m is 0 or 1). The polybenzoxazole precursor is also provided. COPYRIGHT: (C)2009,JPO&INPIT
