It should be noted that the field of view in which the portion where the conductive contact 3 and the terminal 19 are in contact with each other can be seen larger than in the past is apparent from a comparison between FIGS. 3 and 7, as shown in FIG. The viewing angle ⁇ of this embodiment is wider than the conventional viewing angle ⁇ shown in FIG.

The other side is contacted so as to apply a certain pressing force in the vertical direction (vertical direction in FIGS. 3 and 4). As a reaction of the strong pressing force, the conductive contact 3 receives a pressing force vertically upward from the terminal 19, and as a result, the holding substrate 4 that holds the conductive contact 3 has an end portion.
- the holding substrate 4 is warped, and the tip of the conductive contact 3 held on the holding substrate 4 is in contact with the terminal 19.
- the position changes while maintaining the state. Therefore, when the inspection is repeated a number of times, the tip of the conductive contact 3 gradually wears, which has the problem of adversely affecting the performance of the inspection system.
- the fixing member 6 is fixed to the holding substrate 4 at the center side of the holding substrate with respect to the conductive contact 3, and the contact block 5 is attached to the holding substrate 4 Between the two. For this reason, the fixing member 6 applies a pressing force vertically downward to the holding substrate 4 through the contact block 5 in the region where the conductive contact 3 is held. It is possible to function as a reinforcing member that cancels out the vertical upward pressure applied by the terminal 19 from the pressure.

- the material forming the fixing member 6 may be a material having high rigidity, or the thickness of the fixing member 6
- the fixing member 6 as a whole may have a desired rigidity by increasing.
- the structure of the fixing member 6 is devised in order to more reliably suppress the occurrence of warping of the holding substrate 4. That is, as shown in FIG. 4, the fixing member 6 is a force that is fixed to the holding substrate 4 by the screw member 13 at the center side of the holding substrate from the region where the conductive contact 3 is held.
- the holding substrate center side rather than the fixing portion where the fixing member 6 is applied (that is, the region where the screw member 13 is disposed), and the countersink is opposed to the end portion where the conductive contact 3 is held.
- the structure is extended to the end of the substrate.
- the fixing member 6 functions as a reinforcing member even in a region located further to the center side of the holding substrate than the fixing portion with respect to the holding substrate 4, and the warping of the holding substrate 4 is more effective. Can be suppressed.
- FIG. 5 is a schematic diagram for explaining an advantageous advantage and will be described below with reference to FIG.
- the screw member for fixing is arranged so as to penetrate not only the reinforcing member but also the contact block. Needed to remove the screw member.
- the contact block 5 in the present embodiment is arranged at a predetermined position on the holding substrate 4, and in the direction in which the fixing member 6 approaches the holding substrate with respect to the upper surface of the block member 11 forming the contact block 5. It is fixed by applying a pressing force. Therefore, even if the contact block 5 is fixed on the holding substrate 4 by the fixing member 6, it can move relatively freely in the horizontal direction (the horizontal direction in FIG. 5 and the direction perpendicular to the paper surface). Is possible. That is, in this embodiment, when the contact block 5 is replaced, only the contact block 5 is removed with the holding substrate 4 force while the fixing member 6 is fixed to the holding substrate 4 by the screw member 13. It is possible to replace the contact block 5 easily.
- the upper surface and the Z or lower surface of the block member 11 forming the contact block 5 may be a surface having minute irregularities.
- the fixing member 6 when the fixing member 6 is fixed to the holding substrate 4, a frictional force is generated between the holding member 4 and the surface of the holding substrate 4. It is difficult to move horizontally.
- the screw member 13 when the screw member 13 is loosened, the pressing force applied by the fixing member 6 is reduced, so the frictional force is reduced and the contact block 5 is relatively easy to move in the horizontal direction. It becomes.
- the block member 11 is positioned with respect to the holding substrate 4 and the fixing member 6 by using a knock pin.
- the LCD 18 has been described as an example of the inspection target 18.
- the inspection target can have an arbitrary circuit structure. It can be applied to an inspection system for wafers.

And it is possible to enjoy the advantage of the present invention that positioning between the two can be easily performed. Further, regarding the manner in which the fixing member 6 is fixed to the holding substrate 4, a configuration other than the screw member 13 may be used.
- the electrical connection between the wiring structure 12 and the conductive contact 3 may be realized by physical contact between the two, but for example, the conductive contact 3 on the lower surface of the block member 11. It is also possible to form a terminal corresponding to, and to electrically connect the wiring structure 12 and the conductive contact 3 via the terminal.
