Abstract
Abstract A tire air warning apparatus attached to a wheel of the vehicle is disclosed. The apparatus includes a sensor which detects tire air pressure lower than a predetermined value and a transmitter which outputs a signal in accordance with an instruction from the sensor. The transmitter accommodates a transmitting substrate, an electric power source and an antenna electrically connected with the substrate. The transmitter is filled up with a non-conductive resin to fix the substrate, power source and antenna in the transmitter.
