[Problem] To provide a positive-type photosensitive resin composition that is produced with novolac resin and has good mechanical properties and high storage stability. [Means for Solving the Problem] A positive-type photosensitive resin composition, comprising: (a) a novolac resin; (b) a polymer comprising, as a main component, a structure represented by formula (1) below and/or a structure represented by formula (2) below:
(wherein formulae (1) and (2), R 1 and R 2 may be the same or different and each represent an organic group having at least two carbon atoms and a valence of 2 to 8, R 3 and R 4 may be the same or different and each represent hydrogen or a monovalent organic group of 1 to 20 carbon atoms, -NH-R 5 in formula (1) and -CO-R 6 in formula (2) each represent a polymer end group, R 5 and R 6 each represent a monovalent organic group having 2 to 30 carbon atoms which includes an unsaturated hydrocarbon group, n is in the range of 10 to 100,000, 1 and m each represent an integer of 0 to 2, and p and q each represent an integer of 0 to 4, provided that p + q > 0; (c) a quinone diazide compound; (d) an alkoxymethyl group-containing compound; and (e) a solvent.
