<p>In order to provide a technology such that the positions of a plurality of lens sections that are integrally formed can be adjusted highly precisely, this lens drive device is provided with a baseline section, a lens unit, an elastic member, a first and second drive unit, an electricity supply unit, and an electrification control unit. In the lens unit, a plurality of lens units including at least two lens units disposed at positions differing in a first direction are formed integrally. The elastic member is affixed to the baseline section, and supports the lens unit in a manner able to move in a second direction along the optical axis. The first drive unit displaces the first end of the lens unit in the second direction by means of imparting a first drive force. The second drive unit displaces the second end of the lens unit in the second direction by means of imparting a second drive force. The electricity supply unit supplies power that causes the generation of the first and second drive forces by the first and second drive units. The electrification control unit causes a first electrification amount and second electrification amount to differ, and causes a first amount of displacement of the first end in the second direction and a second amount of displacement of the second end in the second direction.</p> |
