A transmitter is adapted to be arranged in a tire to cause a tire pressure warning device to issue a warning. The transmitter includes a transmitting section, which has a terminal, and a pressure switch. The pressure switch includes a hollow box and a passage that causes an interior of the box and an interior of the tire to communicate with each other. The box includes a conductive deforming portion, which is configured to be separate from the terminal when the difference between the pressure in the box and the pressure in the tire is less than a predetermined value and to be elastically deformed to contact the terminal of the transmitting section when the pressure in the box is higher than the pressure in the tire at least by the predetermined value. The transmitting section transmits a warning signal that causes the tire pressure warning device to issue a warning in response to contact between the deforming portion and the terminal.
