Abstract

A camera module is provided, including a prism base, a prism driving mechanism, a prism unit, a lens unit, and an image sensor. The lens unit is disposed on the lens driving mechanism. The prism base includes a metal member, at least one first wiring layer, and a first insulation layer disposed between the metal member and the first wiring layer. The prism driving mechanism is electrically connected to the first wiring layer. The prism unit is connected to the prism driving mechanism, and the prism driving mechanism can drive the prism unit to rotate relative to the prism base. The image sensor can catch the light reflected by the prism unit and passing through the lens unit.

First claim

What is claimed is:

1. A camera module, comprising:
a prism base, comprising:
a metal member;
at least one first wiring layer; and
a first insulation layer, disposed between the metal member and the at least one first wiring layer;

a prism driving mechanism, electrically connected to the at least one first wiring layer; and
a prism unit, connected to the prism driving mechanism, wherein the prism driving mechanism can drive the prism unit to rotate relative to the prism base, and the thickness of the metal member exceeds the total thickness of the first insulation layer and the at least one first wiring layer.

2. The camera module as claimed in claim 1 , wherein the thickness of the metal member is 0.10 mm-0.35 mm.

3. The camera module as claimed in claim 1 , wherein the first wiring layer is formed on the first insulation layer by using a molded interconnect device.

4. The camera module as claimed in claim 1 , wherein the at least one first wiring layer is formed on the first insulation layer by coating.

5. The camera module as claimed in claim 1 , wherein the metal member and the at least one first wiring layer have the same coefficient of thermal expansion.

6. The camera module as claimed in claim 1 , wherein the prism base further comprises:
at least one second wiring layer; and
a second insulation layer, wherein the second insulation layer is disposed between the second wiring layer and the metal member, and the metal member is disposed between the first insulation layer and the second insulation layer.

7. The camera module as claimed in claim 6 , wherein the thickness of the metal member exceeds the total thickness of the second insulation layer and the second wiring layer.
