PROBLEM TO BE SOLVED: To provide an altitude measuring device of moving body capable of highly precisely measuring an altitude of a moving body using a measurement result from an atmospheric pressure sensor carried by the moving body and a measurement result from an atmospheric pressure sensor in an environment. SOLUTION: The altitude measuring device of moving body measures an altitude based on measurement information from the atmospheric pressure sensor (carried type atmospheric pressure sensor) carried by the moving body and the atmospheric pressure sensor (reference atmospheric pressure sensor) placed at a known altitude outside the moving body, includes an atmospheric pressure offset acquisition means between the carried type atmospheric pressure sensor and the reference atmospheric pressure sensor, and measures the altitude of the moving body by an atmospheric pressure difference from both the atmospheric pressure sensors corrected by an atmospheric pressure offset acquired by the atmospheric pressure offset acquisition means.
