Abstract
An optical image capturing module includes a lens assembly and a circuit assembly. The circuit substrate has a through hole. A lower surface of the circuit substrate has multiple circuit contacts. A sensing surface of an image sensing component has multiple image contacts. Each image contact is electrically connected to one of the circuit contacts via a signal transmission element, thereby the sensing surface directly faces the through hole. The lens base made of an opaque material has a receiving hole. The lens assembly includes a lens base disposed on an upper surface of the circuit substrate and a lens group, thereby the sensing surface directly faces the receiving hole via the through hole. The image sensing component is located in the receiving hole. The lens group includes at least two lenses having refractive power, and is disposed on the lens base and is located in the receiving hole.
