PROBLEM TO BE SOLVED: To provide an emergency vehicle travelling location detection apparatus capable of detecting a travelling location of an emergency vehicle highly and precisely with low costs. SOLUTION: A distance between its own vehicle to the emergency vehicle is calculated on the basis of an analysis result of a sound pressure detection part 5 and a road on which the emergency vehicle can travel and the location of the emergency vehicle on the road in a road map acquired from a map data storage part 9 are estimated. Next, when the road on which the vehicle can travel is estimated, a travelling location of the emergency vehicle on the road on which the vehicle can travel is specified on the basis of an analysis result of an alarm frequency by a frequency detection part 7, travelling speed of its own vehicle on the road map and a travelling direction of its own vehicle on the road map.
