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 of a hybrid type made of an inorganic material and an organic material includes a substrate 10 made of the inorganic material, a grid structural body 20 made of the 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 surface of the functional film 30 is rounded and bulges in a width direction of the ridge portions 22. A maximum width (WMAX) of the functional film 30 is more than or equal to a bottom width (WB) of the ridge portion 22.
