Claim:
A pyrromethene-boron complex compound represented by the following formula (1): wherein R 1 to R 6 and Y are independently a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted heterocyclic group, a halogen atom, a haloalkyl group, a carboxyl group, an ester group, a carbamoyl group, an amino group, a nitro group, a cyano group, a silyl group or a siloxanyl group, adjacent substituents of R 1 to R 6 may form a substituted or unsubstituted fused aromatic ring or a substituted or unsubstituted aliphatic ring, X is a carbon atom or a nitrogen atom, and when X is a nitrogen atom, Y is not present, Z 1 and Z 2 are independently a hydrogen atom, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group or a substituted or unsubstituted aryloxy group, at least one of Z 1 and Z 2 is an alkoxy group substituted with a fluorine atom or an aryloxy group substituted with a fluorine atom or a fluoroalkyl group, and Z 1 and Z 2 may form a ring structure.
