A vehicle-mounted apparatus communicates wirelessly with a terminal (user terminal) of a passenger of a vehicle and causes an electric field intensity maintaining unit to store an electric field intensity in wireless communication with the user terminal. The vehicle-mounted apparatus determines whether the user terminal is located in the vehicle based on a value related to a first electric field intensity acquired when a power supply of the vehicle is in a predetermined status and stored in the electric field intensity maintaining unit and based on a value related to a second electric field intensity acquired when the passenger leaves the vehicle and stored in the storage unit. The vehicle-mounted apparatus gives the passenger a predetermined notification when it is determined that the user terminal is located in the vehicle.
