Energy-sensitive composition, cured product, and pattern forming method

An energy-sensitive composition comprising:

• at least one silane compound (A) selected from the group consisting of a silane compound monomer capable of forming a polysilane compound, a silane compound oligomer, and the polysilane compound;
• an acid;
• and
• a base generator (B) represented by the following formula (1):
• wherein, in the above formula, R1 to R11 each independently represents a hydrogen atom, a halogen atom, a nitro group, an alkyl group, an aryl group, an arylalkyl group or an alkoxy group, R5 and R6 may be connected to each other via a single bond or a divalent linking group, Zq+ represents a q-valent counter cation composed of a base having a pKa of 24 or more, and q represents an integer of 1 or more, and
• wherein a content ratio of the base generator (B) to the acid in the composition is base generator (B):acid=1:0.003 to 1:3.5 in terms of a molar ratio.
