Summary:A probe card includes a flexible inorganic material layer, a metal micro structure, and a circuit board. The flexible inorganic material layer has a first surface and a second surface opposite to each other. The metal micro structure is disposed on the first surface. The circuit board is disposed on the second surface, and the circuit board is electrically connected to the metal micro structure. The test signal is adapted to be conducted to the circuit board through the flexible inorganic material layer.
