  [Object] A polarizing element and polarizing plate having improved optical properties and durability. [Solution] A polarizing element characterized in comprising a polyvinyl alcohol resin film formed by adsorbing at least one dichromatic pigment selected from a compound represented by formula (I), a salt thereof, or a transition metal complex, and performing stretching, the polyvinyl alcohol resin film having a degree of polymerization of 5,000 to 10,000 (A represents a nitro group or an amino group; R 1 and R 2 each independently represents a hydrogen atom, a hydroxyl group, a lower alkyl group, a lower alkoxy group, a sulfo group, or a lower alkoxy group having a sulfo group; and X represents an benzoylamino group optionally having a substituent, an phenylamino group optionally having a substituent, an phenylazo group optionally having a substituent, or an naphthotriazole group optionally having a substituent, the substituent being a lower alkyl group, a lower alkoxy group, a sulfo group, an amino group, or a substituted amino group).
