接触子部材、コンタクタ及び接触方法

Document Type and Number:

Japanese Patent JP4545760

Kind Code:

B2

Abstract:

In a contactor contact piece members can be arranged at a fine pitch, and a contact can be made surely by a small contact pressure. The contact piece members electrically connect an electronic part to an external circuit. The contact piece member is formed of an electrically conductive material in a generally spherical shape. A molecular density of a central part of the contact piece member is lower than a molecular density of a part near a surface. The electrically conductive material may include at least one of an electrically conductive fine particle, an electrically conductive fiber and an electrically conductive filler.
