Summary:PROBLEM TO BE SOLVED: To provide an infrared proximity sensor avoiding malfunction even if visible light enters a filter (lens) and reaches a detection part, by integrating/sharing an infrared lens and an LED lens. SOLUTION: An infrared proximity sensor 1 includes a resonance point part of the infrared proximity sensor 1; a detection part 1b detecting a peak value of the resonance point part; a resistance part 1d for multiplying the peak value by a constant resistance value; and a filter 8 through which light of any wavelength is attenuated.
