An inkjet recording apparatus includes a recording head, a housing, a cap unit, a protrusion and a guide part. The recording head has an ink ejecting port on a lower face. The housing supports the recording head. The cap unit includes a cap. The cap unit is inserted into a space below the recording head in a predetermined direction to be attached to the housing and to cover the lower face of the recording head with the cap. The protrusion is protruded from a lower portion of the housing on a rear side in the predetermined direction more downward than the lower face of the recording head. The guide part is formed in an upper portion of the cap unit on the rear side in the predetermined direction and comes into contact with the protrusion so as to guide insertion and removal of the cap unit.
