A positive-type photosensitive composition comprising: (A) a silanol group-containing polysiloxane having a structure obtained by subjecting a compound represented by formula (1) to a compound represented by formula (2) through a hydrolysis-condensation reaction alkane compound, (B) a compound having at least 2 epoxy group-containing organic groups, (C) o-diazinaphthoquinones, and (D) an organic solvent. R 1 represents a C1-4 alkyl group, etc., R 2 represents a C2-10 divalent hydrocarbon group, R 3 represents a C2-10 divalent saturated aliphatic hydrocarbon group, and X represents a compound represented by general formulas (3) to (5). group (see the manual for details). m, n and p represent numbers satisfying that m:n:p is 1:2.1-12:1-6 and m+n+p is 3-6. R 4 represents a C1-4 alkyl group, etc., R 5 represents a C1-4 alkyl group, and a represents 1-2. |
