An integrated loop type vehicle detecting apparatus and a parking information system using the same are provided to improve installation complexity, road cutting problem in installation, line disconnection problem between a loop coil and a vehicle detector, and impossibility in reusing previously installed loop coil. An integrated loop type vehicle detecting apparatus(100) comprises a body portion forming an outer shape of the apparatus. Differential loop coils(101,102) are formed in a closed curve shape at the top and bottom within the body portion. The distances between each loop coils and the vehicle to be detected differ from each other. Since the loop coils are arranged at the top and bottom and difference is generated in the distance to the bottom structure of the vehicle, an inductance evaluation unit(104) increases the vehicle detection sensitivity by using the difference of the change amount in the loop coils. A communication unit(105) receives a vehicle detection result from the inductance evaluation unit and transmits the result to an external device.
