PROBLEM TO BE SOLVED: To provide an electronic azimuth meter capable of calculating an accurate azimuth, by correcting a sensitivity difference between magnetic sensors in respective axes, and by calculating accurately an offset, even when sensitivities of the magnetic sensors arranged in the three-directional respective axes orthogonal each other are different. SOLUTION: This electronic azimuth meter of the present invention is provided with an azimuth arithmetic unit for calculating relative sensitivities of the magnetic sensors arranged in the other two axes, using three-dimensional coordinate values acquired by magnetic sensor output acquisition devices arranged respectively with the magnetic sensors on the three axes orthogonal each other, and using the sensitivity of the magnetic sensor arranged in any one of the three axes orthogonal each other, and for computing the azimuth, using the relative sensitivities.
