Abstract:
1. A probe device which inspects electrical characteristics of an object to be inspected, the probe device comprising: a probe card comprising a support plate which supports a contactor that contacts the object to be inspected, and a circuit board disposed at a top surface side of the support plate; a reinforcing member having a part which is disposed at a top surface side of the circuit board and which reinforces the circuit board; a holding member which holds an outer peripheral portion of the reinforcing member, wherein fixing members are inserted into guide holes, and are fixed to the holding member, the guide holes are formed to pass through the outer peripheral portion of the reinforcing member in a thickness direction of the reinforcing member such that the guide holes guide the reinforcing member when the reinforcing member horizontally extends or contracts, a length in a longitudinal direction of each of the guide holes is greater than a diameter of each of the fixing members when viewed from a plane, a central line passing through a center of each of the guide holes in the longitudinal direction passes through a center of the reinforcing member when viewed from a plane, and in the guide holes, the outer peripheral portion of the reinforcing member is vertically spaced apart from the fixing members.
