A ceramic member was produced from a mixture mainly composed of element.
- Example 3 the same non-swellable My force as in Examples 1 and 2 was applied, and sintering was performed by a hot press sintering method. The sintering conditions during hot press sintering were also the same as in Examples 1 and 2 described above.
- measurements based on JIS R 1618 were performed in different temperature bands on the sintered bodies obtained by sintering using the test pieces 102 and 103 similar to the above. Measurement results The results are shown in Table 3.
- the thermal expansion coefficient of the orientation direction of the ceramic member is 4.0 ⁇ 5 ⁇ 0 ⁇ 10- 6 / ° about C at all temperatures band, the thermal expansion coefficient of silicon (3.4 X 10- A value close to 6 / ° C) is achieved.
- the thermal expansion coefficient of the pressing direction parallel to direction 11; was 12 X 10- 6 / ° about C. Therefore, it has been clarified that the ceramic member according to Example 3 also exhibits anisotropy regarding the thermal expansion coefficient.
- Example 3 in order to confirm the workability of the ceramic member, a ceramic member having a plate thickness of 2.7 Omm was formed from the sintered body, and 1000 through holes were formed in the same manner as in Example 1 above. Was formed in a matrix.
- the hole pitch p was 200 m.
- a pitch accuracy of ⁇ 5 m was achieved.
- the ceramic member produced in Example 3 also had the same workability as the ceramic member produced in Examples 1 and 2 above.
- the present invention provides a probe for electrically connecting a circuit structure to be inspected and a circuit structure for sending a signal for inspection in a micro contactor used for semiconductor inspection or liquid crystal inspection. It is suitable as a material for the probe holder that inserts.
