Provided is a black light-shielding member, which has an excellent effect of anti-reflection that based on low glossiness and has a high blackness. A black light-shielding member including a substrate film, a resin-made light-shielding layer having a concave-convex shape formed on at least one surface of the substrate film, and a blackened layer formed on the resin-made light-shielding layer is produced. By adjusting an arithmetic mean surface roughness Ra of the surface on which the light-shielding layer and the blackened layer are formed to be 0.25 μm or more, and the maximum thickness of the blackened layer is less than the said Ra, a blackness with an L value of 12 or less is achieved.

An electronic device includes a display including a panel layer in which a plurality of pixels are disposed, and a camera module disposed under the display, where the camera module includes an image sensor and a plurality of lenses, and an optical axis of the plurality of lenses passes through the panel layer. A coating layer, which lowers reflectance, is formed on a lens surface of the plurality of lenses when an angle of slope of a partial area of the lens surface is within a specified range. The angle of slope is an angle formed by the lens surface with a normal line perpendicular to the optical axis.

A zoom lens includes, in order from an object side along an optical axis, a first lens group G1 having positive refractive power, a second lens group G2 having negative refractive power, and a third lens group G3 having positive refractive power. Upon zooming from a wide-angle end state W to a telephoto end state T, a distance between the first lens group G1 and the second lens group G2 increases, and a distance between the second lens group G2 and the third lens group G3 decreases. Given conditions are satisfied. Accordingly, a zoom lens having high optical performance with suppressing variations in aberrations, an optical apparatus equipped therewith, and a method for manufacturing the zoom lens are provided.
