PROBLEM TO BE SOLVED: To provide a moving living being detector for detecting precisely a moving living being such as a human body, without being affected by sunshine or the like. SOLUTION: This moving living being detector is constituted of an infrared detecting element constituted to receive an infrared ray in each section from a detection area partitioned into the plurality of sections, and to output a detection signal of a level in response to each received light quantity, a temperature detecting part for acquiring a measured temperature value in the each section, based on the each detection signal, a control part for detecting the moving living being in the detection area, based on the measured temperature value in the each section, and an output part for issuing a living being detection alarm by control of the control part. The detector finds the center coordinate value corresponding to all the sections where a prescribed temperature or more of temperature is detected, acquires a time serial data within a fixed time range from a time serial data of the center coordinate value to find a frequency spectrum thereof, analyzes the frequency spectrum to detect the presence of regularity in a change of the time serial data, and determines the presence of the moving living being when irregular.
