A liquid drop ejecting device includes a housing supporting a plurality of head units that are arranged in two rows to be partially overlapping along a main scanning direction in a staggered configuration. The head unit includes a flow path unit having an ink flow path, a piezoelectric actuator ejecting ink from nozzles in the flow path unit, and a reinforcement plate for reinforcing the flow path unit. In the reinforcement plate, a smaller-width portion and a larger-width portion are disposed along the main scanning direction, such that an end face of the smaller-width portion of the reinforcement member in one row contacts an end face of a reinforcement member in the adjacent row.
