PROBLEM TO BE SOLVED: To provide a filter holder for illumination made of light-weighted flame-retardant paper which is safe even if fallen down, and to provide a stage direction luminaire. SOLUTION: A binder-shaped holder main body, pinching a filter for transmitting lamp light and directing color in exposure at an opening located at the central part, is formed by impregnating aluminum hydroxide in a pulp by 40 to 70 wt.%. By the above, the filter holder for illumination, fulfilling the flame-retardant property and illumination filter detachability, with little danger at fall-down due to light-weight, is obtained.
