As described above, the light from the human body sensing unit 3 disposed on the upper part of the urinal body 1 is directed slightly downward and to the left (or right) with respect to the front direction B of the urinal body 1. 1B, even if the human body sensing unit 3 is at a low position, the light surely hits the foot C and is automatically received by the human body sensing unit 3 as shown in FIGS. 1B and 1C. The operation of the faucet is performed accurately, and the disadvantage that light from a low position passes through between the feet as in the related art can be solved. Moreover, the unit structure in which the human body sensing unit 3 is provided on the upper part of the urinal body 1 allows the human body sensing unit 3 to be attached at the same time when the urinal body 1 is attached. Therefore, as compared with the conventional case where the human body sensing unit is buried in a wall different from the urinal body, the mounting of the human body sensing unit 3 takes less time and effort, and the workability is greatly improved. It is planned. In addition, by arranging the human body sensing unit 3 on the upper edge of the bowl surface 2, there is an advantage that urine is less likely to be applied to the human body sensing unit 3.

According to the present invention, as described above,
Since it is provided with a light emitting element that emits light in a direction inclined to the left or right with respect to the front direction of the urinal body, it is ensured that the inclined light strikes the left or right foot and is received. In other words, even if the light is projected from a low position, the automatic faucet can be reliably operated without the risk of passing through between the feet.
