Research Abstract	This research project aims to develop a technique that thermally treats a polymeric material surface with an irradiation of high power laser to locally form an electrically conductive layer. The relationship between the condition of laser irradiation and the obtained electrical conductivity was discussed by using a simulation model of heat transfer, and an appropriate condition of the thermal treatment was shown. Another type of formation technique was also investigated by irradiating the laser to Ag nano-ink spread on a substrate of polymeric material, and the appropriate condition for the electrically conductive layer formation was experimentally explored.
