Disclosed is a dye that absorbs light in a wide wavelength range reliably and efficiently, and a method for producing the same. The dye of the present invention comprises a first dye and a second dye that absorb light in different wavelength regions, and the first dye and the second dye are chemically bonded by a covalent bond. Has been. The first dye is a metal complex dye or an organic dye. The metal complex dye is selected from the group consisting of a ruthenium complex dye, an osmium complex dye, a copper complex dye, a rhenium complex dye, and an iron complex dye. The organic dye is a predetermined triphenylamine dye or a predetermined coumarin dye. The second dye is a macrocyclic compound in which nitrogen-containing heterocyclic compounds are linked. The macrocyclic compound has a skeleton of any one of a porphyrin skeleton, a phthalocyanine skeleton, and a naphthalocyanine skeleton, and a metal atom is coordinated at the center of any of the skeletons.
