Patent ID: 7898272

Claim:
A probe card that houses a plurality of probes for electrically connecting a semiconductor wafer as a test object and a circuit structure for generating a signal for a test, the probe card comprising: a flat wiring board that has a wiring pattern corresponding to the circuit structure; an interposer that is stacked on the wiring board and relays wirings of the wiring board; a space transformer that is stacked on and fastened to the interposer, transforms a space between the wirings relayed by the interposer, and leads the wirings out to a surface opposite a surface facing the interposer; a probe head that is stacked on the space transformer and houses and holds the probes; and a resist layer on surfaces of the interposer and the space transformer facing each other, the resist layer surrounding where electrical connection is established between the interposer and the space transformer, wherein the interposer and the space transformer, when stacked, are bonded by an adhesive, and wherein the adhesive is applied to surfaces of the interposer and the space transformer facing each other except where electrical connection is established between the interposer and the space transformer.
