The base is provided with at least two supporting protrusions (222) extending therefrom. Each protrusion is oriented the lens module, and the lens module is fixedly to and contacts with the at least two supporting protrusions. A colloid layer surrounding the sensor is sandwiched between the second end of the holder and the base. Electronic components are disposed on the circuit board and covered by the colloid layer. ## Claims ### Claim 1 A camera module comprising: a lens module; a base provided with at least two supporting protrusions extending therefrom, each protrusion oriented toward the lens module and integrally formed with the base, each protrusion comprising a top supporting surface, and the lens module being fixedly supported on and contacting with the top supporting surface of each of the at least two supporting protrusions; a sensor directly attached to the base; and a colloid layer surrounding the sensor, wherein the colloid layer is sandwiched between the lens module and the base. ### Claim 2 (depends on 1) The camera module as claimed in claim 1, wherein the at least two supporting protrusions and the base are separately formed and then assembled together. ### Claim 3 (depends on 1) The camera module as claimed in claim 1, wherein the lens module comprises: a lens barrel; at least one lens received in the lens barrel; and a holder having a first end for holding the lens barrel and an opposite second end, the holder defining a cavity therein, the cavity extending through the first end and the second end, and the second end of the holder being attached to the base by fixedly contacting with the at least two supporting protrusions. ### Claim 4 (depends on 3) The camera module as claimed in claim 3, wherein the first end has threads defined on an inner wall thereof, and the lens barrel has threads defined on an outer wall thereof, and the lens barrel thereby threadedly engages with the inner wall of the first end of the holder. ### Claim 5 (depends on 3) The camera module as claimed in claim 3, further comprising a transparent component provided between the sensor and the lens barrel. ### Claim 6 (depends on 5) The camera module as claimed in claim 5, wherein the transparent component is an infrared filter attached to the sensor. ### Claim 7 (depends on 5) The camera module as claimed in claim 5, wherein the transparent component is a glass plate attached to the sensor. ### Claim 8 (depends on 5) The camera module as claimed in claim 5, wherein the transparent component is an infrared filter fixed to an inner wall of the second end of the holder. ### Claim 9 (depends on 3) The camera module as claimed in claim 3, wherein the colloid layer is sandwiched between the second end of the holder and the base. ### Claim 10 (depends on 9) The camera module as claimed in claim 9, wherein the colloid layer is a thermosetting adhesive. ### Claim 11 (depends on 1) The camera module as claimed in claim 1, wherein a cross sectional shape of the at least two supporting protrusions is selected from the group comprised of square, rectangular, triangular, at least partially circular/arcuate. ### Claim 12 A camera module comprising: a circuit board provided with at least two supporting protrusions extending therefrom; a sensor attached on the circuit board; a colloid layer attached on the circuit board with the supporting protrusions extending through the colloid layer in a direction perpendicular to the circuit board, wherein the colloid layer surrounds the sensor; and a lens module comprising a lens barrel, at least one lens received in the lens barrel and aligned with the sensor, and a holder having a first end for holding the lens barrel and an opposite second end being fixedly attached to the at least two supporting protrusions and cooperating with the circuit board to sandwich the colloid layer therebetween. ### Claim 13 (depends on 12) The camera module as claimed in claim 12, wherein a plurality of electronic components is disposed on the circuit board and covered by the colloid layer. ### Claim 14 (depends on 13) The camera module as claimed in claim 13, wherein the circuit board is rectangular, the at least two supporting protrusions are formed at corners of the circuit board, the colloid layer is rectangular and defines at least two openings at corners thereof, the at least two supporting protrusions extending through the at least two openings to contact with the opposite second end of the holder. ### Claim 15 (depends on 13) The camera module as claimed in claim 13, wherein the circuit board is rectangular, the at least two supporting protrusions are rectangular parallelepiped in shape and disposed at opposite sides of the circuit board, the colloid layer is rectangular and defines at least two openings thereof, the at least two supporting protrusions extending through the at least two openings to contact with the opposite second end of the holder.
