Each of first and second filters included in the filters includes a first reflective layer, a second reflective layer, and an intermediate layer therebetween and has a resonance structure having resonant modes whose orders are different from each other. A refractive index and/or a thickness of the intermediate layer in the first and second filters is different depending on the filter. A transmission spectrum of each of the first and second filters has local maximum value of transmittance at each of wavelengths included in a wavelength region, and the wavelengths correspond to the resonant modes, respectively.
