Abstract
An object detecting device includes a detector and a determination unit. The detector detects presence or absence of an object based on whether a receiving unit that converts a mechanical vibration into an electric signal receives a reflected ultrasonic wave transmitted intermittently from a transmitting unit. The determination unit determines that the transmitting unit is normal when the electric signal is not detected in a determination section set within a predetermined time from a starting time point of the transmission of the ultrasonic wave. The determination unit determines that the transmitting unit is abnormal when a correlation value of waveforms of a plurality of electric signals detected in the plurality of determination sections is greater than or equal to a specified value. The determination unit determines that the transmitting unit is normal when the correlation value is less than the specified value.
