Abstract
An interference filter is fixed with respect to a base substrate by a fixing member which is disposed on one portion which is on the outer side of a filter region. Accordingly, since the periphery end of the interference filter, other than a portion (end portion) in which the fixing member is disposed, becomes a floated state (free end), it is possible to suppress the warping of the interference filter even when there is the difference in coefficients of thermal expansion with the base substrate. Further, spacer portions which are lower than the height of the fixing member are formed outside the filter region and on the portion separated from the fixing member. At the time of the impact, since the spacer portions come in contact with the base substrate to function as stoppers, it is possible to suppress occurrence of peeling-off or cracks on the fixing member.
