To provide a probe in which deposit of an oxide film formed on the surface of an electrode part of an object to be measured is restrained to eliminate erroneous judgement, which is easy in maintenance, and which has a long life, and a manufacturing method thereof.

Molding dies 8a, 8b are prepared to pressure-mold one end part of a wire rod 2. A knife edge part 10 including a clearance part 9 for escaping a portion of the wire rod 2 compressed by pressurization to be extended is provided in the molding dies 8a, 8b. The one end part of the wire rod 2 is inserted between the molding dies 8a, 8b, and pressure is applied to the molding dies 8a, 8b to conduct pressurization-work to the one end part of the wire rod 2. The portion of the wire rod 2 compressed by the pressurization to be extended comes into the clearance part 9, and a probe with the prescribed shape of knife edge part formed in the one end part of the wire rod 2 is provided after the pressurization molding.
