Functional contactor

A functional contactor comprising:

• a conductive elastic portion configured to come into electrical contact with one among a circuit substrate of an electronic device, a bracket coupled to the circuit substrate, and a conductor contactable with a human body, wherein the conductive elastic portion has an elastic force;
• a substrate comprised of a plurality of dielectric material layers;
• and
• a functional element including a first electrode electrically connected in series to the conductive elastic portion, and a second electrode disposed to be opposite to the first electrode at a predetermined interval,
• wherein the plurality of dielectric material layers are disposed between the first electrode and the second electrode, a first dielectric material layer, a second dielectric material layer, and a third dielectric material layer are sequentially stacked on the second electrode, and the second dielectric material layer is made of sintered ceramic having a high dielectric constant that is higher than that of each of the first dielectric material layer and the third dielectric material layer.
