Abstract
A dielectric layeris formed on a region including grid-shaped convex portionsof a resin substratehaving the grid-shaped convex portionswith pitches of 80 nm to 120 nm on its surface, and metal wiresare formed on the dielectric layer. It is thereby possible to obtain a wire grid polarizer having a microstructural concavo-convex grid with pitches of the level of 120 nm or less that has not been implemented.
