SOLUTION: There is provided an aromatic-substituted xanthene dye represented by the following formula. (Y1 and Y2 each independently represents hydroxyl, oxygen, iminium, a linking group or an amine; Y1 forms a cyclic amine together with R2 or Y2 forms a cyclic amine together with R3; R2, R3, R5 and R7 each independently represents H, F, Cl, a lower alkyl, a lower alkene, sulfonate, sulfone, iminium, amide, nitrile, a lower alkoxy, phenyl or a linking group; R1 represents a single ring or a polycyclic aromatic or the like; R4 represents H, F, alkyl, amino or the like; and R6 represents acetylene, a lower alkyl or the like.)
