The present invention improves the adhesion between the substrate 10 and the easily-adhesive layer 20 and the adhesion between the easily-adhesive layer 20 and the functional layer 30, so that sufficient adhesion is maintained even in a long exposure under severe environments such as high temperature and high humidity. The purpose. In order to achieve this object, the functional member of the present invention is a functional member in which an easily-adhesive layer 20 and a functional layer 30 are stacked in this order on at least one side of a substrate 10, and the easily-adhesive layer 20 The composition to be formed contains a polyester-acrylic composite resin having a glycidyl group, and the solid content acid value of the composition is 2.5 to 6.0 mgKOH/g, and the composition for forming the functional layer 30 is glycidyl It contains a compound having a functional group reactive with a diyl group, and the solid content acid value of the composition is 4.0 mgKOH/g or less. |
