Electrode, the electrode photoelectric conversion device and a method

There is provided a micro electrode comprising a photoelectric conversion device and a manufacturing method of the microelectrodes. Forming in the substrate a plurality of parallel groove portions and a region sandwiched between the groove portion, and the resin is supplied to the conductive portions and the grooves and the fixing region, thereby filling the resin with a conductive groove portions and a conductive resin covers the region. Provided electroconductive resin does not extend outwardly to form an electrode and may have a design width. Is formed on a region sandwiched between the groove portion of the electrode portion, the cross-sectional area whereby the minor axis direction may be large, low resistance can be obtained in the longitudinal direction.
