An image pickup apparatus includes: an image pickup device disposed in a first principal surface of a silicon substrate, the image pickup device sensing infrared light; an electrode pad disposed on the first principal surface; a front-face wiring connecting the image pickup device and the electrode pad; an external connection terminal disposed on a second principal surface of the silicon substrate; a back-face wiring connecting the electrode pad and the external connection terminal via a substrate through-hole extending from the second principal surface side through the silicon substrate to a back face of the electrode pad; and a light blocking layer disposed on the second principal surface, the light blocking layer covering a trench portion surrounding the image pickup device and a region surrounded by the trench portion.
