Image sensor module and camera module

An exemplary image sensor module includes a plate, an image sensor, and a number of conductive wires. The plate includes a top surface, a bottom surface, a light passing through hole, a number of spaced receiving holes extending through the top surface and the bottom surface, and a number of conductive pads on the top surface. The receiving holes surround the through hole. The sensor includes a first surface and a number of bonding pads corresponding to the respective conductive pads. The first surface opposes the bottom surface, and is mounted on the bottom surface. The first surface includes a light sensitive region aligned with the through hole, and a light insensitive region surrounding the light sensitive region. The bonding pads are arranged on the light insensitive region. The wires pass through the respective receiving holes, and respectively electrically connect the bonding pads to the corresponding conductive pads.
