The present technology relates to a camera module, a method of manufacturing the same, and an electronic apparatus capable of suppressing generation of a ghost or a flare. The camera module includes an image sensor, a lens unit that is provided on a light receiving surface of the image sensor, and at least one refractive index adjustment layer that is formed between the image sensor and the lens unit. The present technology can be applied to, for example, a camera module including a complementary metal oxide semiconductor (CMOS) image sensor.
