Abstract
A spectroscopic sensorcomprises a plurality of interference filter unitsA,B,C, having a cavity layerand first and second mirror layersopposing each other through the layer, for selectively transmitting therethrough light in a predetermined wavelength range according to an incident position thereof; a light-transmitting substrate, arranged on the first mirror layerside, for transmitting therethrough the light incident on the unitsA,B,C; and a light detection substrate, arranged on the second mirror layerside, for detecting the light transmitted through the unitsA,B,C. The second mirror layersare separated for the respective unitsA,B,C. The cavity layeris formed integrally over the unitsA,B,C, while a part of the layerenters a region between the second mirror layersadjacent to each other.
