PROBLEM TO BE SOLVED: To execute focus detection by a focus detector whose assembly cost is low and which does not choose an assembling worker. SOLUTION: This focus detector is provided with an energizing member 80 integrally energizing an optical member nearest to a photographing lens out of the optical members of the focus detector, for example, an infrared cut filter 100, and a bending member 120 for bending an optical path such as a mirror to a holding member 50. Thus, the member 120 is stuck to the member 50 while it is eternally or temporarily restricted, and the filter 100 and the member 120 are fixed, thereby performing the focus detection by the focus detector whose assembly cost is low and which does not choose the assembling worker. |
