Patent ID: 8012870

Claim:
A wiring method between steps in which a step portion is covered by an insulating slope formed by providing and drying droplets of an insulating ink in which an insulating material is dispersed in a dispersion medium and a wiring line formed by drying and firing provided droplets of a conductive ink in which a conductive material is dispersed in a dispersion medium is laid out between the steps and passes on a top surface of the insulating slope, the method comprising: covering a surface including the step portion where the wiring line to be laid out by a liquid repellent layer formed of a liquid material repelling the dispersion medium of the insulating ink; forming a plurality of dot lines including a plurality of dots by arranging a plurality of droplets of a resin ink including a resin material on a surface of the liquid repellent layer so as not to contact with each other in a region partitioned by a side serving as a start point and a side serving as an end point in a direction in which the wiring line is laid out, and by hardening the arranged droplets; and drying droplets of the insulating ink provided to the step portion so as to connect the dot lines, wherein the wiring line between the steps is laid out so as to pass on a top surface of the insulating slope.
