PROBLEM TO BE SOLVED: To provide an inkjet recording apparatus which can inexpensively record a high-quality image by preventing an ink mist from adhering to an ejection port, and preventing an influence on the flying of an ink liquid droplet. SOLUTION: This inkjet recording apparatus comprises an inkjet head 24, and an alternating array electrode 26 which is arranged in such a manner as to face an ink ejection surface of the inkjet head. The electrode 26 comprises: a first electrode piece which comprises a plurality of linear tooth portions arranged at predetermined intervals in parallel with one another, and a base portion connected to ends of the plurality of tooth portions; and a second electrode which comprises a plurality of linear tooth portions arranged at predetermined intervals in parallel with one another, and a base portion connected to ends of the plurality of tooth portions, and in which the tooth portion is arranged between the tooth portions of the first electrode piece. The inkjet recording apparatus satisfies the expression: 0.5≤(D/L)≤2.0. In the expression, D represents an interval between the tooth portions adjacent to each other, and L represents the shortest distance between an ink liquid droplet ejection position of the inkjet head and the tooth portion.
