Patent ID: 7629807

Claim:
An electrical test probe comprising: a plate-shaped main portion having a base end to be attached to a support board and a tip end opposite said base end, said main portion being made of a tenacity material; and a probe tip portion arranged at said tip end of said main portion and having a probe tip to contact an electrode of a device under test, wherein said main portion further includes a conductive material extending from said base end to said tip end, at least part of said conductive material being buried within said tenacity material, wherein said tenacity material has higher resiliency than that of said conductive material while said conductive material has higher conductivity than that of said tenacity material, wherein said main portion includes a plate-shaped seat region having said base end, a plate-shaped arm region extending in a cantilevered manner in a first direction from an end portion opposite said base end side of said seat region, and a plate-shaped tip end region protruded from the tip end of said arm region in a second direction intersecting with said first direction and having said tip end, and wherein said arm region includes a pair of first and second arm portions spaced from each other in said second direction by an elongated hole penetrating said arm region in its thickness direction and extending in said first direction and is electrically short-circuited by a low resistance material extending in said first direction within said elongated hole from one end portion to another end portion of said elongated hole in its longitudinal direction.
