摘要

A composition for forming a passivation layer, the composition containing: at least one type of alkoxide represented by general formula (I); at least one compound selected from among a titanium compound, a zirconium compound, and a silicon alkoxide; a solvent; and a resin. General formula (I) is M(OR1)m (wherein, M represents at least one metal element selected from among Nb, Ta, V, Y and Hf; R1 represents a C1-8 alkyl group or a C6-14 aryl group; and m represents an integer between 1 and 5).
