Sensor driving device having substrate with electromagnetic driving unit and protrusion part and camera module having same

A sensor driving device comprising:

• a first substrate;
• a second substrate disposed above the first substrate and electrically connected with the first substrate;
• a first driving unit disposed on the second substrate;
• and
• a second driving unit corresponding to the first driving unit;
• an image sensor disposed on the second substrate,
• wherein the second substrate comprises a body and a first protrusion part protruding from one end of the body,
• wherein the first protrusion part comprises a first extension part extending from the body in a first direction away from the first substrate, and a second extension part extending from the first extension part in a second direction different from the first direction,
• wherein the first driving unit comprises six magnets,
• wherein the second driving unit comprises six coils corresponding with the six magnets,
• wherein four magnets of the six magnets are disposed adjacent to four corners of the image sensor, respectively, and
• wherein the remaining two magnets of the six magnets are disposed between the four magnets.
