Abstract
In order to provide an anisotropic conductive sheet which can be applied to more finely and more narrowly pitched electrodes and also to provide spring electrodes applied for the anisotropic conductive sheet, the spring electrodes manufactured as follows. A part having a bending leaf spring shape is formed out of a monocrystal silicon by anisotropic etching and gold is plated on the surface of the part so as to obtain a silicon spring electrode. The silicon spring electrodesare inserted in through holes formed on a silicone rubber sheet and fixed to the through holes.
