A photoresist includes a three-layer structure of a lower layer, a middle layer and an upper layer, wherein the lower and upper layers are photoresist layers, the lower layer is sensitive to a light having a longer wavelength than a light to which the upper layer is sensitive, and the middle layer is a light-shielding film formed of an organic substance that has a transmittance such that the lower layer is not exposed to lights to which the lower and upper layers are sensitive.
