体検知器。[Scope of Claim for Utility Model Registration] In a human body detector that has a hemispherical condensing cover whose inner surface is formed into a stepped lens and a sensing element installed inside the condensing cover, The stepped lens is formed concentrically so that it is non-directional in the circumferential direction, and the sensing element receives only a portion of the light in the circumferential direction of the light collecting cover. A human body detector comprising scanning means for moving a part of the circumferential direction that receives light along the circumferential direction.
