A polarizing element which has a base material that contains an azo compound represented by formula (1) or a salt thereof in the form of a free acid. (In the formula, each of Ay1 and Ay2 independently represents an optionally substituted naphthyl group or an optionally substituted phenyl group; each of m and n independently represents 0 or 1; and each of Ry1 to Ry10 independently represents a hydrogen atom or a substituent.) L'invention concerne un élément polarisant comprenant un matériau de base qui contient un composé azoïque représenté par la formule (1) ou un sel de celui-ci sous la forme d'un acide libre. (Dans la formule, Ay1 et Ay2 représentent chacun indépendamment un groupe naphtyle éventuellement substitué ou un groupe phényle éventuellement substitué ; m et n représentent chacun indépendamment 0 ou 1 ; et Ry1 à Ry10 représentent chacun indépendamment un atome d'hydrogène ou un substituant.) 遊離酸の形式で、下記式（１）で表されるアゾ化合物又はその塩を、基材に含む偏光素子。（式中、Ａｙ１又はＡｙ２は各々独立に、置換基を有してもよいナフチル基、又は置換基を有してもよいフェニル基を表し、ｍ又はｎは各々独立に０又は１であって、Ｒｙ１～Ｒｙ１０は各々独立に水素原子又は置換基を表す。）
