PROBLEM TO BE SOLVED: To provide an inkjet recording head having a damper mechanism capable of effectively exhibiting a damping effect associated with a pressure variation of an ink by spreading the ink over a wide range in an ink reservoir. SOLUTION: In the damper mechanism 13, an ink ejection port 21 is disposed at an end on an upper side (side in a direction shown by an arrow A) in a vertical direction of the ink reservoir 16, whereby the ink is spread over the wide range in the ink reservoir 16, and the damping effect associated with the pressure variation of the ink is effectively exhibited.
