Abstract

The present invention has an object to obtain a polyimide film that has a sufficiently smooth surface without peeling even in a case where the polyimide film is a thick film and that is excellent in adhesion to an inorganic substrate. An alkoxysilane-modified polyamic acid solution of the present invention contains: an alkoxysilane-modified polyamic acid; and a surface control agent, the alkoxysilane-modified polyamic acid solution having a specific viscosity, the alkoxysilane-modified polyamic acid being obtained by reacting a polyamic acid with an alkoxysilane compound containing an amino group, and the polyamic acid being obtained by reacting a diamine with a tetracarboxylic dianhydride.
