摘要： A camera module includes a PCB (Printed Circuit Board) installed with an image sensor, a base mounted on the PCB, and a bobbin reciprocatingly mounted above the base. A bottom elastic member is fixed to the base to support the bobbin, and a terminal is installed at the base, one end of which is conductively connected to the PCB and the other end of which is conductively connected to the bottom elastic member at a solder part. A solder cut-off part is formed at the base to cut off movement of overflowing solder from the solder part.
