An imaging device includes an optical filter. The optical filter has a configuration in which a polarization filter layer and a spectral filter layer are laminated in light transmission direction. Of the polarization filter layer and the spectral filter layer, the layer on the lower side in lamination direction has an uneven top face in the lamination direction. The optical filter is formed by filling the uneven top face with a predetermined filling material so as to even out the top face and then forming other layer.
