PROBLEM TO BE SOLVED: To provide a magnetic field measurement apparatus easy to operate and equipped with analog outputting function etc., of effective value to an external apparatus and capable of displaying effective value of each axis in various mode, as well as resultant effective value of the X-axis, Y-axis and Z-axis components. SOLUTION: The magnetic field measurement apparatus for calculating the prescribed parameters of the magnetic field to be measured comprises three coils 11 of X-axis coil 11x, Y-axis coil 11y and Z-axis coil 11z for detecting the magnetic field; the integrator 21 and an A/D converter 24 are at least included in each measurement system of each coil 11; the operation controller 25 for receiving the output voltage of each coil 11 via the integrator 21 and the A/D converter 24 for calculating the prescribed parameters of the magnetic field; and the analogue output part 40 for outputting the analog signal in each coil system 11 to an external apparatus.
