Patent ID: 6967493

Claim:
A probe card for measuring electrical characteristics of a semiconductor device, the probe card comprising: electrical wiring; electrodes that are electrically connected to said electrical wiring; contactor mounting substrates comprising mounting holes to mount contactors; and a plurality of contactors that are integrally molded by well-conducting metal material and that connect between an electrode of the object to be tested and the said electrodes on the said contactor mounting substrate; wherein said contactors comprise: an insertion part having spring characteristics, wherein the insertion part comes in contact with the inside of the mounting holes with pressure being inserted into the contactor mounting holes on the contactor mounting substrate; a support part for supporting the insertion part and performing positioning in the height direction by contacting a surface of the contactor mounting substrate; an arm part having spring characteristics and extending from the support part; and a contact part arranged at a tip end of the arm contact part to come in contact with the electrode of an object to be tested.
