PURPOSE: A reinforced probe needle for controlling thickness thereof, a fabricating method thereof, and a probe card are provided to fabricate the probe needle having a thickness less than 100 micrometers by controlling a diameter of the probe needle within a range between 25 micrometers and 125 micrometers. CONSTITUTION: A probe needle for probe card includes a core and a conductive layer. The core(110) is formed with a fine glass fiber. The conductive layer(120) is formed around the core. The conductive layer is formed with one selected from Au, Ti, Al, and W. The core has a diameter of 20 to 100 micrometers. The conductive layer has a thickness of 3 to 30 micrometers. An insulating layer is partially formed on an outer surface of the conductive layer.
