A positive type photosensitive resin composition contains (a) a quinone diazido phenolic resin represented by the formula: <IMAGE> (I) wherein R1 is an alkyl group having 1 to 4 carbon atoms, R2 is a bivalent hydrocarbon residue having 5 to 16 carbon atoms provided that groups bound to R2 do not bind with the same carbon atom of R2, D1, D2 and D3 and are the same or different groups and each represent a hydrogen atom or a quinone diazido unit represented by <IMAGE> <IMAGE> provided that a molar ratio of the hydrogen atom to the quinone diazido unit is 0 to 10, m is a number of 0 to 10, n is a number of 1 or 2, and l1, l2 and l3 are the same or different numbers and each represent a number of 1 to 3; and (b) an alkali-soluble resin.
