This electric linear actuator (40) comprises a fixed block (50), an output movable block (60), a pair movable block (70), a projection-side connecting component (80), a retraction-side connecting component (90), a block coupling component (100), and an output functional component (200). By means of the electromagnetic force between the fixed block (50), the output movable block (60) and the pair movable block (70) reciprocate in the movable direction (DX) in mutually opposite phases. The projection-side connecting component (80) is coupled with the output movable block (60) and the pair movable block (70). The retraction-side connecting component (90) is coupled with the output movable block (60) and the pair movable block (70). The projection-side connecting component (80) and the retraction-side connecting component (90) have mutually different shapes.
