PROBLEM TO BE SOLVED: To provide a liquid droplet delivering device which can measure the ink pressure in the vicinity of a recording head, and can perform highly responsive and accurate pressure control by disposing a pump in the vicinity of the recording head. SOLUTION: Since a pressure sensor S3 is an element utilizing the MEMS technology and is small, it can be disposed in the vicinity of an inkjet head 64 in a head unit 66. Since a micro-pump P3 is an element utilizing the MEMS technology and is small, it can be disposed in the vicinity of the inkjet head 64 and the pressure sensor S3 in the head unit 66.
