摘要： PROBLEM TO BE SOLVED: To reduce influence of noise generated other than from an object 1 to be measured. SOLUTION: External noise and noise generated from motors 111, 112 and 182 are cut by a shielding metallic case 100 and a metallic member 181 to reduce the influence of the noise to be applied to a probe antenna 2 or the object 1 to be measured. Then, the probe antenna 2 is used to measure an intensity of an electromagnetic field generated from the object 1 at each measurement coordinate, obtaining an electromagnetic field distribution. Since the correct near electromagnetic field distribution having the reduced influence of the noise can thus be obtained by using no large-sized facilities such as an open site or an anechoic chamber, development/design of an electronic appliance can be inexpensively and easily carried out.
