To provide a collision detecting apparatus for a vehicle, including an integrating member for cumulatively integrating an output from an acceleration sensor when the output exceeds a specific calculation start level, and a collision detecting member for outputting a collision signal when a cumulative integral value calculated by the integrating member exceeds a threshold value, wherein the collision detecting apparatus is intended to accurately perform a collision decision by preventing the occurrence of an erroneous detection based on a vibration waveform of acceleration of the vehicle as a result of, for example, riding past a stepped portion. The collision detecting apparatus includes a vibration waveform detecting means W for detecting that an output waveform from the acceleration sensor S is a specific periodical vibration waveform. When the vibration waveform detecting member W detects the vibration waveform, the integrating member does not stop the cumulative integration even if the output G returns to a specific calculation end level G0 and continues the cumulative integration for the output G that contains not only an output component corresponding to a negative acceleration but also an output component corresponding to a positive acceleration.
