PROBLEM TO BE SOLVED: To precisely and continuously measure a magnetic vector on a plane or curved face of a complicated shape in the vicinity of measuring objects, by setting an optional operation mode preliminarily. SOLUTION: This measuring instrument is provided with a multiaxial magnetic sensor 1 for measuring a dynamic change of a magnetic field in the vicinity of the measuring objects, and for measuring concurrently three-axis-directional components of the peripheral magnetic field, and support bodies 23, 24, 25 for supporting the multiaxial magnetic sensor 1 and the measuring objects 31, 31. The respective support bodies are moved at the prescribed operation modes by stepping motors 26, 27, 28. A sensor output acquiring means 65 reads out collectively measured values of the three-axis-directional components of the multiaxial magnetic sensor 1. A magnetic vector drawing means 68 acquires a magnetic vector found based on the measured values of the three-axis-directional components, and a relative positional data between the measuring object and the multiaxial magnetic sensor, and executes continuously processing for drawing the magnetic vector in the vicinity of the measuring objects, by an image data.
