PROBLEM TO BE SOLVED: To provide a method of determining a reflective face of a reflecting mirror of a luminaire for a vehicle and a luminaire for a vehicle with an appropriate appearance which can efficiently determine a reflective face satisfying required light-distribution conditions with effective use of light from a light source as reflected light. SOLUTION: A plurality of reflective areas are generated by segmenting the inside of a reflective face outline 100, and an aimed reflective angle as a reflective condition is set for each reflective area. While making the direction of the reflective angle a basic reflective direction, each surface shape for partial reflective faces 210 to 242 is formed so that each adjacent partial reflective faces are suitably connected, and at the same time, gradually changing faces 311, 312 are formed between the partial reflective faces. With this, a suitable total appearance is maintained while a plane shape for a reflective face 10a satisfying required light distribution conditions is obtained. |
