CONDUCTIVE BASE MEMBER AND MULTILAYER CONDUCTIVE BASE MEMBER

Abstract

To provide a flexible conductive base member and a multilayer conductive base member including the same, having no problem of failing to function as a contact and causing a variation in height between contacts.

There are a covered region 10 covered with a noble metal and a non-covered region 20 not circumferentially covered with a noble metal on a surface of a reticulated fibrous body 50. The covered region 10 is located at an intersection 7 of fibers 5 of the reticulated fibrous body 50, and the intersections 7 are connected to each other. The non-covered region 20 is located between the intersections 7 of the fibers 5 of the reticulated fibrous body 50.

Claims

1. A conductive base member comprising: a covered region covered with a noble metal; and a non-covered region not covered with a noble metal on a surface of a reticulated fibrous body, wherein the covered region is formed at an intersection of fibers of the reticulated fibrous body, and the intersection is electrically short-circuited, and the non-covered region is formed between the intersections of the fibers of the reticulated fibrous body, and the portion between the intersections is electrically opened.

2. The conductive base member according to claim 1, wherein the non-covered region is formed by chemical treatment or mechanical treatment.

3. The conductive base member according to claim 1, wherein the reticulated fibrous body is a fibrous body in which a non-covered region is formed on a noble metal fiber covered with a noble metal.

4. The conductive base member according to claim 1, wherein the reticulated fibrous body is a fibrous body in which a non-covered region is formed between intersections of noble metal fibers covered with a noble metal on a mixture of the noble metal fibers and a non-noble metal fiber not covered with a noble metal.

5. The conductive base member according to claim 1, wherein the reticulated fibrous body is a fibrous body in which, on a fibrous body of a non-noble metal fiber not covered with a noble metal covered with a noble metal, a non-covered region is formed between intersections of fibers of the fibrous body covered with the noble metal.

6. A multilayer conductive base member formed by stacking the conductive base member according to claim 1.
