Patent ID: 7106080

Claim:
A probe card comprising: a contactor comprising: an insertion part comprising spring characteristics, wherein the insertion part is configured to pressure-contact an inside of contactor mounting holes in the contactor mounting substrate when inserted into the contactor mounting holes; a supporting part configured to support the insertion part and restrict the insertion depth of the insertion part into the contactor mounting holes in the contact mounting substrate by contacting a surface of the contactor mounting substrate; a holding part which is integrated with the supporting part, and wherein the holding part holds the inserting part as the inserting part is being inserted into the contactor mounting holes in the contactor mounting substrate; a pressurized part which is integrated with the holding part, and wherein the pressurized part is pressurized for inserting the insertion part into the contactor mounting holes in the contactor mounting substrate; an arm part which extends from the holding part, wherein the arm part comprises spring characteristics; and a contact part which is located at a tip end of the arm part, wherein the contact part is contacted with an electrode of the object to be tested.
