A photosensitive polyimidosiloxane obtained by polymerization and chemical imidation of an aromatic tetracarboxylic dianhydride having two benzene rings bonded either directly or via CO or O, and an aromatic diamine with a photosensitive group and a diamine which includes diaminopolysiloxane. It may be used to form films with large thicknesses and excellent photocuring properties and solubility in organic solvents, while high-temperature heat treatment thereof is unnecessary and the electrical and mechanical characteristics of its cured films are satisfactory.
