Abstract:
A contact structure for establishing electrical connection with contact targets, comprising:a contact substrate made of silicon or ceramic having through holes; and a plurality of contactors where each of the contactors has a hook shape and is comprised of a tip portion provided at one end of the contactor and is oriented in a vertical direction to form a contact point, a base portion provided at another end of the contactor oriented in a direction opposite to said tip portion and is inserted in a through hole provided on the contact substrate, and a curved portion provided between the tip portion and the base portion having a semi-circular shape and produces a contact force when the contactor is pressed against the contact target; wherein said contact point of said tip portion is sharpened, and said base portion of the contactor has a straight body which is inserted in a through hole of the contact substrate in such a way that an end surface of said base portion is projected from the bottom surface thereof to function as a contact pad for electrical communication with an external component.
