The C-SnO2 mixed particles and C-Ni mixed perticles have been implanted into a poly(oxymethylene) substrate and a poly(phenylene sulfide) thermoplastic resin substrate by using a laser-assisted powder jet for the formation of the resistances by those particles. These mixed powders were jetted using Ar gas and were implanted into the substrate by irradiating a green laser of CW type with powers of 210, 480, and 700 mW on the substrate kept at a constant moving speed. The laser was condensed at the same or nearly the same spot as the powder jetted on the substrate. It was found that the values of conductance and conductivity changed by the implantation of the powder of the weight fraction of SnO2 or carbon in the substrate in the wide range of 6 orders, and that the logarithm of these conductance and conductivity was proportional to the weight fraction of carbon and SnO2, which showed the percolation phenomenon in the two mixed particles system. The resistance showed similar frequency dependence to the commercial carbon resistance. There was little frequency change of the implanted resistance using the ditch compared with that without the ditch.
