Patent ID: 7688092

Claim:
A measurement board for electrically connecting an electronic device under test and a test apparatus, comprising: a base board having a contactor to which the electronic device under test is to be electrically connected mounted on its front surface, and having a signal conductor interconnect electrically connected to the contactor and formed on its front surface; a coaxial connector to which a coaxial cable electrically connecting the measurement board and the test apparatus is connected, passing through the base board from its back surface toward its front surface, and having a front exposed part of a center contact bent and electrically connected to the signal conductor interconnect; and a cover member covering and contacting at least part of the front exposed part of the center contact, wherein the cover member has a first conductor interconnect arranged in parallel with a contact portion of the front exposed part which contacts the cover member and a first dielectric arranged between the contact portion of the front exposed part and the first conductor interconnect, and a main surface of the first conductor interconnect faces the contact portion of the front exposed part.
