Claim:
A carboxylic acid compound represented by the following formula (I), a salt thereof, or an ester thereof wherein R 1 represents a C 1-6 alkoxy group; L represents a single bond or a C 1-6 alkylene group which may have one or more substituents selected from C 1-6 alkyl groups; M represents a C 1-6 alkylene group: T represents a single bond, a C 1-3 alkylene group, or a C 2-3 alkynylene group; W represents a carboxyl group; represents a single bond or a double bond; X is a group represented by the formula: wherein n represents 1 to 5; R X2 and R X3 are the same as or different from each other and each represents a hydrogen atom, a hydroxy group, a halogen atom, a C 1-6 alkoxy group, or a C 1-6 hydroxyalkyl group, provided that at least one of R x2 and R x3 in the compound is a group other than a hydrogen atom; and Q 3 and Q 4 are the same as or different from each other and each represents an oxygen atom or (O)S(O); Y is a phenyl group or a C 3-7 alicyclic hydrocarbon group, each of which may have one to 4 substituents selected from the group consisting of halogen atoms, cyano groups, C 1-6 alkyl groups, C 1-4 alkoxy groups, C 1-6 haloalkyl groups, and C 1-6 hydroxyalkyl groups; and the ring Z is a phenyl group.
