A portable electronic device and an image-capturing module thereof are provided. The image-capturing module includes a circuit substrate, an image-capturing chip, a plurality of first conductive materials, a filter component, a plurality of second conductive materials, and a lens assembly. The circuit substrate includes a plurality of substrate bond pads. The image-capturing chip includes a plurality of chip bond pads. The first conductive materials are respectively disposed on the chip bond pads. The filter component is disposed on the first conductive materials, and the filter component includes a light-transmitting body and a plurality of conductive structures disposed on the light-transmitting body and respectively electrically connected to the first conductive materials. Each of the second conductive materials is electrically connected between the corresponding conductive structure and the corresponding substrate bond pads. The lens assembly is disposed on the circuit substrate so as to correspond to the image-capturing chip.
