To provide a dielectric characteristics measuring jig, a dielectric characteristics measuring device and a dielectric characteristics measuring method with which it is possible to measure dielectric characteristics with high accuracy.SOLUTION: A dielectric characteristics measuring jig 1 is a measuring jig used to measure the dielectric characteristics of samples 101, 102 by a disk resonator method. The dielectric characteristics measuring jig 1 comprises: an upper conductor 21 (first conductor) and a lower conductor 22 (second conductor) facing each other and capable of holding the samples 101, 102 therebetween; a middle conductor 23 (third conductor) provided in the samples 101, 102; an upper stationary plate 31 (first stationary plate) provided on the top side of the upper conductor 21 (the side opposite to the sample 101); a lower stationary plate 32 (second stationary plate) provided at the underside of the lower conductor 22 (the side opposite to the sample 102); and conductor pressuring means 6 for applying a load in a direction in which the upper conductor 21 and the lower conductor 22 are brought closer to each other within the range of the upper conductor 21 in a plan view.SELECTED DRAWING: Figure 1
