PURPOSE: To accurately form a crossover insulating layer on the periphery of a soldering electrode land by forming an insulating layer simultaneously with a crossover region on the peripheral region near at least the crossover region of a soldering electrode land which is disposed near at least the crossover region.
CONSTITUTION: First crossover glass paste is printed on a crossover region 4 and the part of the periphery of a soldering electrode land 3, dried and baked to form a first crossover insulating layer 5. Part of a first wiring conductor film 2 is covered with the layer 5 and the periphery of the region near the crossover region 4 of the land 3 is also covered therewith. Accordingly, it operates as the function of a solder resist layer. When the paste for forming the layer 5 is printed, the rugged part of the region near the land 3 is small. Thus, squeegee is in close contact with a substrate 1, and an accurate pattern is printed with less sag to prevent the paste from adhering to the land 3.
