An optical device () includes a joining structure in which a first conductive film () and a second conductive film () are joined to each other. The first conductive film () that constitutes the joining structure is constituted by a conductive material. The second conductive film () that constitutes the joining structure is constituted by a metal material. Apart of the second conductive film () comes into contact with the first conductive film (). A plurality of concave portions are provided in a contact surface of the second conductive film () which comes into contact with the first conductive film (). The contact surface has a surface roughness greater than a surface roughness of a non-contact surface of the second conductive film () which does not come into contact with the first conductive film ().

An optical device () has a joining structure in which a first conductive film () and a second conductive film () are joined to each other. The first conductive film () that constitutes the joining structure is constituted by a transparent conductive material and the like. In addition, the second conductive film () that constitutes the joining structure is constituted by a metal material. A transition region, in which the transparent conductive material and the metal material are mixed, exists between the first conductive film () and the second conductive film (). The transparent conductive material includes, for example, a conductive polymer.

The first conductive film (), which constitutes the joining structure, is constituted by a transparent conductive material and the like. The second conductive film (), which constitutes the joining structure, is constituted by a metal material. A dispersing agent, which is constituted by a material different from the transparent conductive material, exists at a portion of the first conductive film () which is located at the periphery of the second conductive film ().
