PROBLEM TO BE SOLVED: To provide an installation angle calculation device capable of calculating accurately the installation angle of a casing of an electronic device without using another expensive sensor having a function for calculating an altitude variation or the like, in an actual traveling state not only in the state where a moving body is traveling on a horizontal plane or in the state where a vehicle is stopped on the horizontal plane. SOLUTION: This installation angle calculation device 1 is equipped with a uniaxial angular speed sensor 10 for detecting the angular speed of the moving body, a speed sensor 11 for generating a vehicle speed pulse wherein a pulse period is changed corresponding to the traveling speed of the vehicle, an acceleration sensor 12 for detecting the acceleration of the moving body, and a curved/direct advance determination means 14 for determining the traveling state of the moving body. An installation angle operation means 13 calculates the installation angle when the moving body advances directly, and verifies whether a value calculated at a curve traveling time is accurate or not.
