Zusammenfassung:	A distance measuring device is provided at low cost. The distance measuring device includes an avalanche photodiode, a TIA, and damping circuits. The avalanche photodiode detects pulsed light that is reflected from an object to be measured. The TIA is an amplifier circuit that converts electric current output from the avalanche photodiode into a voltage signal. The damping circuits and are arranged in a rear stage of the TIA and convert pulse signals into signals with a damped oscillation waveform. The signal path from the avalanche photodiode to the TIA allows a direct current signal to pass therethrough.
