A vehicle surroundings monitoring apparatus capable of distinguishing and determining an object type with high reliability, particularly a vehicle surroundings monitoring apparatus capable of determining an object by distinguishing between a pedestrian and other objects among the objects with high reliability. The vehicle surroundings monitoring apparatus detects an object existing around a vehicle (10) from images obtained by cameras 2R and 2L mounted on the vehicle (10) and includes an object extraction process unit (steps 1 to 9) which extracts an object from the image, a width calculation process unit (steps 101 to 104) which calculates widths of the object in a plurality of height positions spaced at vertical intervals of the object extracted by the object extraction process unit, and an object type determination process unit (step 105) which determines the type of the object based on the widths calculated by the width calculation process unit.
