Abstract
An optical module (colorimetry sensor) includes an interference filter, and a transparent substrate to which a first substrate of the interference filter is fixed, having a second thermal expansion coefficient which has a value different from a first thermal expansion coefficient. The interference filter is fixed to the transparent substrate through an adhesive layer made of gel-like resin, and the adhesive layer alleviates stress generated due to a difference in the thermal expansion coefficients between the interference filter and the transparent substrate.
