<p>A conductive contact, wherein a holder (1) is formed by stacking support bodies (3, 4, 5) on each other and providing holder holes (2) so as to pass through the support bodies, needle bodies (9, 10) are installed at the ends of coiled springs (8) and the needle bodies (9) on one sides are prevented from being extracted by one of the support bodies, a length (L) between flange parts (9b) accepted by the large diameter holes (2b) of the holder holes (2) and the tips of needle parts (10a) and the depth (D) of the large diameter holes (2b) of the holders (1) are set generally identical to each other, since the coiled springs (8) are thus brought into a generally no-load state, even when at least one side needle bodies (9) are prevented from being extracted from the corresponding end parts of the holder holes (2), the portions thereof for preventing the coiled springs (8) from being extracted do not receive the compressive loads of the coiled springs, whereby even when the support bodies are thin, the deformation and deflection of the holders can be avoided and a material with a low coefficient of thermal expansion such as a ceramic material can be used for the holders.</p> |
