This negative photosensitive resin composition comprises an epoxy group-containing resin, a metal oxide, and a cationic polymerization initiator (I). The cation polymerization initiator (I) is characterized by containing one or more selected from the group consisting of compounds represented by general formula (I1) and compounds represented by general formula (I2). In formula (I1), R b01 -R b04 each represent an optionally substituted aryl group or a fluorine atom. In formula (I2), R b05 represents an optionally substituted fluorinated alkyl group or a fluorine atom. The plurality of R b05 may be the same or different from one another. q represents an integer of one or greater. Q q+ represents a q-valent organic cation. |
