Abstract
An optical filter including a near infrared absorbing layer on a glass substrate, in which adhesiveness between the glass substrate and the near infrared absorbing layer is firm, high reliability is enabled in uses under a high temperature and high humidity environment, and manufacturing yield is secured, and a high reliability solid-state imaging device having the optical filter are provided. An optical filter includes: a glass substrate; and a near infrared absorbing layer formed on one principal surface of the glass substrate, wherein the near infrared absorbing layer is obtained by reacting a composition for forming the near infrared absorbing layer on the glass substrate and the composition contains a transparent resin having a fluorene skeleton and a reactivity group; a near infrared absorbing dye; and a silane coupling agent and/or oligomer thereof having a hydrolyzable group and a functional group which have reactivity for the reactivity group.
