Abstract: Provided is a wire grid polarizing element excellent in heat dissipation and excellent in transmissivity and polarization splitting properties for oblique incident light at wide-range incident angles. A wire grid polarizing element 1 includes a substrate 10 made of an inorganic material, a grid structural body 20 made of an organic material and including a base part 21 provided on the substrate 10 and a plurality of ridge portions 22, the base part and the ridge portions being integrally formed, and a functional film 30 made of a metal material and covering part of the ridge portion 22. The ridge portion 22 has an upward narrowing shape that narrows in width with distance from the base part 21. The functional film 30 covers and wraps the top of the ridge portion 22, and does not cover a bottom side of the ridge portion 22 and the base part 21. A coverage rate (Rc) of the side surface of the ridge portion 22 obtained by the functional film 30 is more than or equal to 30% and less than or equal to 70%. The organic material is a cured product of a light curing acrylic resin for imprinting containing a photopolymerization component.
