Claim:
1. A positive photosensitive resin composition comprising: (A) a polymer compound containing a carboxyl group and a siloxane chain; (B) a photosensitive material capable of generating an acid by light and increasing a dissolution rate in an aqueous alkaline solution; (C) one or more crosslinkers selected from an amino condensate modified by formaldehyde or formaldehyde-alcohol, a phenol compound having on average two or more methylol groups or alkoxymethylol groups per molecule, a polyhydric phenol compound in which a hydrogen atom of a phenolic hydroxyl group is substituted by a glycidyl group, a polyhydric phenol compound in which a hydrogen atom of a phenolic hydroxyl group is substituted by a substituent shown by the formula (C-1), and a compound having two or more nitrogen atoms bonded to a glycidyl group per molecule and shown by the formula (C-2); and (D) a solvent; wherein the component (A) is obtained in the presence of an acid catalyst by condensation of at least a siloxane compound having phenol groups at both terminals and shown by the formula (1), either or both of a phenol compound shown by the formula (2) and a phenol compound shown by the formula (3), and one or more kinds of aldehydes and ketones shown by the formula (4), wherein the dotted line represents a bond; R wherein R wherein “b” is 1 or 2; and X represents a divalent organic group when “b” is 1, or X represents a trivalent organic group when “b” is 2, wherein when “b” is 1, the carboxyl group may be directly bonded to the phenol group without intervention of X, wherein “c” is 1 or 2; and Y represents a monovalent substituent selected from a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a hydroxyl group, and a halogen atom when “c” is 1, or Y represents a divalent organic group optionally containing an atom of Si, S, or O when “c” is 2, wherein R
