Carboxylic acid or carboxylic acid ester compound having fused-ring structure, method for producing the same, and use of compound

A method for producing a compound represented by General Formula (A1-1), the method comprising:

• obtaining a compound represented by General Formula (A1-1) by subjecting (i) an ethylenically unsaturated carboxylic acid compound, (ii) an ethylenically unsaturated carboxylic acid ester compound, (iii) an ethylenically unsaturated dicarboxylic acid anhydride, or (iv) an alkylcarboxylic acid ester compound having a leaving group at a ω-position to an addition reaction with a compound represented by General Formula (SA1-1) in the presence of a base,
• in the formulae, R5 and R6 each independently represent a hydrogen atom or an alkyl group, L1 and L2 each independently represent an alkylene group having 1 to 6 carbon atoms, and Spa and Spb each independently represent a single bond or a divalent linking group,
• R11 and R21 each independently represent a substituent, and v1 and w1 are each independently an integer of 0 to 4,
• provided that in General Formulae (SA1-1) and (A1-1), a structure represented by (R11)v1-benzen ring/cyclopentadiene skeleton/naphthalene ring-(R21)w1 is not line-symmetrical, where “/” represents that the two rings described on left and right sides of the structure are fused.
