PROBLEM TO BE SOLVED: To provide a high frequency device that can realize a filter having a desirably excellent characteristic and easily adjust the pass frequency of the filter with high accuracy. SOLUTION: The high frequency device is provided with a filter element consisting of resonance elements 12 configured with a superconductive film formed on a substrate 11, with a dielectric board 15 that is opposed to the surface of the substrate 11 with the superconductive film formed thereon nearly in parallel and placed to cover gaps among the resonance elements, and with an interval adjustment member 16 that moves the dielectric board to adjust the interval between an opposed face of the dielectric board to the substrate and the surface of the substrate with the superconductive film formed thereon. The minimum distance between the interval adjustment member and the resonance elements is selected to be at least thrice or over of a pattern width of the superconductive film configuring the resonance elements.
