Abstract
A lead-free super-highly conductive plastic is formed of a conductive resin composition which includes a thermoplastic resin, a lead-free solder that melts during plasticization, and metal powder or a mixture of metal powder and metal short fibers that promotes the fine dispersion of particles of the lead-free solder within the thermoplastic resin. In the lead-free super-highly conductive plastic, since particles of the lead-free solder are connected with each other via solder melted within the plastic, the particles of the lead-free solder are mutually joined, so that high conductivity is attained.
