PROBLEM TO BE SOLVED: To provide a receiving antenna of a tire pressure alarm device using a radiating leaky coaxial cable capable of improving the reception performance of measured data of radio transmission when a transmitter performs the radio transmission of the measured data of tire pressure measured by a temperature sensor and a pressure sensor in a tire by constituting the receiving antenna of the tire pressure alarm device using radiating leaky coaxial cable (RCX). SOLUTION: In the tire pressure alarm device including sensors for measuring temperature, pressure, etc. of the inside of the tire, a transmitter for transmitting through radio the data measured by the sensors to the outside of the tire after the measured data is modulated to a UHF band, a receiver for receiving the measured data transmitted through radio from the transmitter, and a display device for displaying the measured data received by the receiver on a LCD screen so as to be browsed by a driver, the receiver changes freely its position and is connected to a cable type antenna for improving a reception rate of the measured data relating to the temperature, the pressure etc. of the tire, which are transmitted by radio to the outside of the tire from the transmitter after being modulated to the UHF band.
