Abstract
A piezoelectric actuator includes a piezoelectric element layered in a pillar shape, and electrode plates located on side surfaces of the piezoelectric element and electrically connected to internal electrode layers of the piezoelectric element. Each of the electrode plates includes a body portion extending in a layering direction of the piezoelectric element and a lead portion that extends in a direction intersecting the layering direction and is electrically connected to a lead terminal. The lead portion includes, in at least one side portion, a recessed portion recessed in a width direction of the lead portion.
