Lens holder driving device capable of preventing deformation due to heat

A lens holder driving device comprising:

• a lens holder in which a lens assembly is mounted;
• a driving coil fixed to said lens holder at outside circumference thereof;
• a magnet opposite to said driving coil;
• a yoke including said magnet;
• an elastic member supporting said lens holder in a direction of an optical axis of said lens assembly shiftably;
• and
• a base disposed at a lower side of said lens holder,
• wherein said elastic member comprises a lower elastic member disposed at a lower side of said lens holder, said lower elastic member comprising first and second leaf spring pieces into which said lower elastic member is divided,
• wherein said lens holder driving device further comprises first and second electrode terminals for feeding said driving coil via said first and second leaf spring pieces,
• wherein said first and second leaf spring pieces have first and second terminal connection portions which are electrically connected to said first and second electrode terminals by soldering, respectively, and
• wherein each of said first and second terminal connection portions has a connection edge forming portion having a connection surface in which edges are formed.
