Optical component driving apparatus and camera module

An optical component driving apparatus comprising:

• a base member;
• an optical component holding member provided movably with respect to the base member having an opening penetrating therethrough in a vertical direction, the opening being configured to accommodate an optical component therein;
• a cover member having a top plate facing the base member in the vertical direction, with the optical component holding member interposed therebetween, the cover member having an upper outer peripheral wall part including a plurality of upper lateral plates extending downward from an outer edge of the top plate;
• and
• a plurality of shape memory alloy wires arranged inside the upper outer peripheral wall part, an end of each of which being fixed to a fixed member including the base member, another end of each of which being fixed to a movable member including the optical component holding member, and each of which being configured to move the optical component holding member with respect to the base member,
• wherein the fixed member includes a case member with an open top configured to house the base member,
• wherein the case member has a bottom plate arranged at a bottom of the base member and a lower outer peripheral wall part including a plurality of lower lateral plates extending upward from an outer edge of the bottom plate, and
• wherein the plurality of lower lateral plates are positioned between the plurality of shape memory alloy wires and the plurality of upper lateral plates constituting the upper outer peripheral wall part, and face the plurality of shape memory alloy wires.
