PROBLEM TO BE SOLVED: To easily fix a plastic filter without occupying a space when the filter is to be attached to a holder. SOLUTION: The holder 2 has a housing part 3 in which an IR cut filter member 1 in a rectangular form is slid and housed and has a stopping means 10 to prevent the filter member 1 in the housed state from dropping from the housing part 3. For example, a push pin 10a is fitted to an insertion hole 10b to prevent the filter member 1 from dropping. The filter is held while the corner 1a of the filter member 1 is exposed from the housing part 3. Thus, the filter can be disposed without occupying a space.
