Probe device having a structure for being prevented from deforming

摘要

A reinforcing member is formed at a top surface side of a probe card including a support plate for supporting a contactor and a circuit board. A plurality of long guide holes are formed in an outer peripheral portion of the reinforcing member. Fixing members fixed to a holding member and collars formed around outer circumferences of the fixing members are formed in the guide holes. A length in a longitudinal direction of each of the guide holes is greater than a diameter of each of the collars, and a central line in the longitudinal direction of each of the guide holes passes through a center of the reinforcing member. Due to the guide holes, horizontal expansion of the reinforcing member itself is allowed.
