PROBLEM TO BE SOLVED: To provide a photosensitive thermosetting resin composition, superior in shelf stability, and also in solvent resistance and insulation property. SOLUTION: The photosensitive thermosetting resin composition contains an alkali-soluble resin, a protective type photosensitive material which controls the solubility of the alkali-soluble resin in an aqueous alkali solution and makes the solubility of the alkali-soluble resin enhanced in the aqueous alkali solution, when it is irradiated with light or a negative type photosensitive material which lowers the solubility of the alkali-soluble resin in the aqueous alkali solution, when it is irradiated with light and a crosslinking compound of formula (1) (where A is an organic residue, having at least two O atoms at the end; X is halogen, hydroxy or the like; and (n) is an integer of >=2). |
