Abstract
An analysis device for analyzing components contained in an object includes a light emitting unit that irradiates the object with light, a transmissive spectral filter, a light detector including a plurality of light receiving elements, an analysis unit. The spectral filter includes a substrate having light transmissivity and being disposed on a light path of the light after being reflected by the object or the light after passing through the object, a plurality of raised portions formed with a metal material on one surface of the substrate, and a metal oxide film including a metal oxide material having a higher refractive index than the metal material, so as to cover the plurality of raised portions and the one surface of the substrate.
