An image pick-up apparatus includes a lens module, a base plate, and an image sensor. The lens module includes a lens barrel and an optical lens received in the lens barrel. The base plate has two opposite surfaces and a rectangular through hole defined between the two surfaces. The image sensor is fixed to the base plate. The image sensor has a top surface facing the lens module. The top surface includes a rectangular exposed portion in the through hole. The exposed portion includes a rectangular optically effective region configured for capturing images. A distance between neighboring long sides of the optically effective region and the exposed portion being greater than 0.47 times of a length of the through hole, and a distance between the neighboring short sides of the optically effective region and the exposed portion being greater than 0.27 times of the length.
