摘要:
A camera module, in which a recessed portion that has a greater depth than the thickness of an imaging device is disposed on the surface (top surface) of an embedded-component substrate. An imaging device is bonded to a bottom of the recessed portion such that an opening is present between the surface (top surface) of the imaging device and the surface (top surface) of the embedded-component substrate. Connection pads on the imaging device are connected to conductor pads disposed on the surface (top surface) of the embedded-component substrate by bonding wires that go through the opening.
