Energy-sensitive composition, cured product, and forming method of patterned cured product

An energy-sensitive composition comprising a polysilane (A), a base generator (B), and a solvent (S),

• wherein the base generator (B) comprises a compound represented by formula (b1), and a photo base generator,
• wherein Rb1 to Rb3 each independently represents a hydrogen atom, a halogen atom, a hydroxyl group, a mercapto group, a sulfide group, a silyl group, a silanol group, a nitro group, a nitroso group, a sulfonato group, a phosphino group, a phosphinyl group, a phosphonato group, or an organic group;
• Rb4 and Rb5 each independently represents a hydrogen atom, a halogen atom, a hydroxyl group, a mercapto group, a sulfide group, a silyl group, a silanol group, a nitro group, a nitroso group, a sulfino group, a sulfo group, a sulfonato group, a phosphino group, a phosphinyl group, a phosphono group, a phosphonato group, or an aliphatic group;
• and
• Rb6 represents a hydrogen atom, an alkyl group, or an alkoxy group.
