Abstract: A photosensitive resin applied onto a substrate is exposed using a mask. In this exposure step, by appropriately setting the size of each light transmitting portion formed in the mask and an exposure gap, an exposure intensity profile on a surface of a photosensitive resin is formed so as to have an increasing and decreasing curve along the surface thereof. When the exposure is performed in accordance with the exposure intensity profile, followed by development, a resin layer having surface irregularities is formed. Subsequently, a reflection layer made of a metal thin film or the like is formed on this resin layer.

As a result, the base layer does not peel from the substrate when developing the photosensitive material which becomes the base layer.
