PROBLEM TO BE SOLVED: To mount an optical filter at low cost without play. SOLUTION: A light shielding cover 30 is fixedly arranged in front of a CCD element 14 through a lens holder 20. A storage opening part 34 for storing the optical filter 40 is formed in the light shielding cover 30, and an abutting part 35 and an engagement projecting part 38 are formed on the inner peripheral part of the storage opening part 34. The engagement projecting part 38 is provided with an elastic piece 37 and the engagement projecting part 38 projecting inward at the tip part of the elastic piece 37, and the engagement projecting part 38 is provided with an inclined energizing surface 38a. By pressing the optical filter 40 into the storage opening part 34, the peripheral edge part on one surface side of the optical filter 40 comes into contact with the abutting part 35, and also, the energizing surface 38a comes in contact with the peripheral edge part on the other surface side of the optical filter 40 so as to energize the optical filter 40 toward the abutting part.
