Claim:
A positive photosensitive resin composition comprising: a resin comprising a structural unit having an acid dissociative group and a structural unit having a functional group capable of forming a covalent bond by reacting with a carboxyl group or a phenolic hydroxyl group; and an acid generator represented by the following formula (I): wherein in formula (I), R 1 represents a hydrogen atom, an alkyl group, an alkenyl group, an alkoxy group, an alkoxycarbonyl group, an acyl group, a carbamoyl group, a sulfamoyl group, a sulfo group, a cyano group, an aryl group or a heteroaryl group; R 2 represents an alkyl group or an aryl group; each of R 3 and R 4 independently represents a hydrogen atom, an alkyl group, an alkenyl group, an alkoxy group, an alkoxycarbonyl group, a carbonyl group or an aryl group; X represents —O—, —S—, —NH—, —NR 5 —, —CH 2 —, —CR 6 H— or —CR 6 R 7 —; each of R 5 to R 7 independently represents an alkyl group or an aryl group; and R 1 and any one of R 5 to R 7 , or R 3 and R 4 , may be bonded to each other to form a ring.
