Abstract: A contactor for connection and signal transfer between conductors includes: a core part configured to extend in a longitudinal direction, contain a conductive particle and be formed to be elastically deformable; an insulation part configured to surround a transverse surface of the core part and be formed to be elastically deformable; and a shield part configured to surround a transverse surface of the insulation part to be spaced apart from the core part, contain a conductive particle and be formed to be elastically deformable.

Abstract: A flexible contactor that electrically connects a pad of an inspection target object with a pad of an inspection device includes, a first elastic part configured to contain a first conductive particle and be formed elastically deformable; and a second elastic part, which is connected in parallel to the first elastic part in a longitudinal direction, configured to contain a second conductive particle and be formed elastically deformable. The first elastic part and the second elastic part are different from each other in at least one of physical properties including hardness, Young's modulus, and resistivity.
