PROBLEM TO BE SOLVED: To provide a dissimilar metal junction probe pin, in which a contact part is made of metal which is different from a main part, which is resistant to heat influence during manufacturing and has excellent durability. SOLUTION: The dissimilar metal junction probe pin is made by joining tip junction metal, which is different from the main part, to a tip part of the main part made of W, Re-W, Be-Cu, or the like. The main part 1 and the tip junction metal 2 are joined by an ultrasonic vibration type junction apparatus 20. After the joining, the tip junction metal 2 and a junction part 3 are sharpened together with (the tip part of) the main part 1 to form the tip contact part of the probe pin.
