摘要:
An anode substrate constituted of a conductive film forming substrate and a reinforcing substrate having different thermal expansion coefficient and being bonded together by the arrangement of adhesive layers is disclosed. The substrate can prevent creation of cracks on the conductive film forming substrate when heating and cooling the anode substrate. The adhesive layers are arranged at an interval, each of the adhesive layers being formed into a shape selected from a group consisting of a rectangular strip shape and a curved strip shape. The adhesive layers are arranged in a pattern to be symmetry with respect to a center line of the arrangement of the adhesive layers extending perpendicular to a line connecting both longitudinal ends of the arrangement of the adhesive layer. Furthermore, the adhesive layers include an outer adhesive portion located outward among remaining adhesive layers, and the outer adhesive layers are arranged shorter than the remaining adhesive layers.
