Abstract
An electrically conductive connecting member includes an electrically insulating elastomer and an electrically conducting elastomer. The conductive connecting member has a Shore Hardness type A from 5 to 90 degrees, water-resistant ability up to 0.1 kgf/cm2 and 10%˜20% compression set. The conductive connecting member is capable of remaining good resilience, water-resistance and electric conductivity after long term use.
