A wavelength selection filter includes a first high refractive index section with a thickness T1, a second high refractive index section with a thickness T2, a high refractive index layer with a refractive index n1, a projection-depression structure layer with a refractive index n2, a filling layer with a refractive index n3, a first high refractive index section with an area ratio R1, and a second high refractive index section with an area ratio R2. With n1>n2, n1>n3, and R1+R2>1, the value of T1×{n1×R1+n2×(1−R1)} is a first parameter, the value of T2×{n1×R2+n3×(1−R2)} is a second parameter, and the ratio of the second parameter to the first parameter is 0.7 or more and 1.3 or less.
