A camera module includes an imaging lens assembly, an image sensor and an optical plate. The image sensor is disposed on an image surface of the imaging lens assembly. The optical plate is disposed between the imaging lens assembly and the image sensor, and includes a substrate and at least one anti-reflection layer. The substrate has an object-side surface and an image-side surface, the object-side surface faces towards an object side, the image-side surface faces towards an image side, and the object-side surface is parallel with the image-side surface. The at least one anti-reflection layer is disposed on the object-side surface or the image-side surface of the substrate, the anti-reflection layer includes a nanocrystal structure layer and an optical-connecting layer, wherein the nanocrystal structure layer includes a metal oxide crystal, the optical-connecting layer connects the substrate and the nanocrystal structure layer.
