Patent ID: 7924038

Claim:
A probe comprising a base portion having an attaching end, said base portion extending in a direction away from said attaching end, an arm portion extending from said base portion in a direction almost orthogonal to the extending direction of said base portion, a probe tip portion protruded from said arm portion and having a probe tip protruded from a protruding end of said probe tip portion, and an alignment mark for alignment of said probe tip of said probe tip portion, wherein: said arm portion has a flat surface area on the opposite side to a side where said attaching end of said base portion is located, said probe tip portion is formed to be protruded from a part of said flat surface area, and an alignment mark surface of said alignment mark is constituted by at least another part of said flat surface area; said flat surface area of said arm portion is a lower surface of said arm portion, and said lower surface is located on said arm portion on the opposite side of a side where said attaching end of said base portion is located and is formed in a rectangular flat surface shape extending along the extending direction of said arm portion; said probe tip portion is formed on said lower surface to separate said lower surface in the extending direction of said arm portion into one or more flat surface area parts, and said alignment mark is constituted by a first flat surface area part of the one or more flat surface area parts into which said lower surface is separated by said probe tip portion; said probe tip portion is formed to be spaced apart from an extending edge of said arm portion, and the first flat surface area part is located between said extending edge and said probe tip portion on said lower surface of said arm portion; and said probe tip portion has a side wall proximate to said first flat surface area part constituting said alignment mark and standing up from said first flat surface area part, and a portion of said side wall proximate to said first flat surface area part extends in a longitudinal direction along a recessed curved line opened toward said first flat surface area part.
