Patent ID: 8766658

Claim:
A probe configured to test electrical characteristics of an object to be tested, the probe comprising: a contact member configured to be brought into contact with the object; and a conductive member configured to be electrically connected with the contact member, wherein a plurality of contact particles having conductivity are distributed in the contact member and a part of at least one of the contact particles protrudes from a first surface of the contact member configured to face the object, the conductive member having elasticity is placed on a second surface of the contact member which is opposite to the first surface, the conductive member includes a plurality of conductive particles having a lower electrical resistance than the plurality of contact particles, and each of the plurality of contact particles has a sharp fragmental surface facing the object for penetrating an oxide film on the object, and when the at least one of particles protruding from the first surface of the contact member are separated or lost by abrasion, contact particles within the contact member form a new front end so that sharp fragmental surfaces thereof are exposed.
