PROBLEM TO BE SOLVED: To realize a wiring structure wherein the wiring damage hardly happens and its manufacturing method. SOLUTION: Columnar protrusions 4 resulting from projected parts of a layer insulation film 2 are formed on the surface of the layer insulation film 2, and a wiring 3 is formed on the layer insulation film 2 so as to cover the columnar protrusions 4. Compared with a wiring formed on a flat layer insulation film, the contact area of the wiring 3 with the layer insulation film 2 is wide to increase the adhesion degree of both, resulting in that the wiring damage hardly happens. The columnar protrusions 4 function like posts against the wiring 3 and hence the wiring damage hardly happens. |
