PROBLEM TO BE SOLVED: To estimate an electric field or a magnetic field at a desired distance from an electric field or a magnetic field which is measured near an apparatus without using an anechoic chamber or the like. SOLUTION: A distance from an electronic apparatus as an object to be measured is designated as r, a measuring wavelength is designated asλ, and the effective maximum dimensions of a measuring apparatus are designated as D. The electric field or the magnetic field is measured in a plurality of points inside a region which satisfies r>λ/2πand r<2D2/λ. A maximum value is detected, or a plurality of wave sources are calculated backwards, and a far field is measured.
