The light absorption energy of the outer dye layer is equal to or higher than that of the inner dye layer, an energy-releasing wavelength of the outer dye layer overlaps with an energy-absorbing wavelength of the inner dye layer, the sensitizing dyes constituting the inner dye layer include an anion and/or betaine dyes, the dyes constituting the outer dye layer include an anion and cation dyes, and the anion dye is more than the cation dye in terms of an addition amount and/or an adsorption amount.
