PROBLEM TO BE SOLVED: To provide device and method for discriminating a two wheeler capable of smoothly passing, while exactly discriminating the type (bicycle or motorcycle) of the two wheeler to pass an entrance/exit, etc. of a bicycle parking lot. SOLUTION: A first sensor to be turned ON by detecting a tire part of the passing two wheeler, regardless of the type of the two wheeler, is arranged in midway of a passage at the entrance/exit of the bicycle parking lot. A second sensor for detecting presence or absence of an object to pass a prescribed height on an upper side of the first sensor is arranged on the height. When the second sensor detects the absence of the object when the first sensor is in an ON state, the bicycle is discriminated, while the motorcycle is discriminated when the second sensor detects the presence of the object when the first sensor is in an ON state.
