PROBLEM TO BE SOLVED: To provide a constituent constituent that enables bias impedance matching with a high precision. SOLUTION: This constituent 100 is inserted into the hole of a multi-layered board to enable impedance matching in the board. The constituent 100 comprises a conductive ground core 102 penetrating and extending multiple layers, a dielectric layer 104 laterally surrounding the conductive ground core 102, and a signal conductive layer 106 laterally connected to the dielectric layer 104.
