PROBLEM TO BE SOLVED: To provide a liquid delivering head in which even if thermal expansion is generated in a member supporting a valve during delivering liquid, a highly accurately stable adhering condition having little influence on the supported valve can be obtained and a stable delivering operation can be performed thereby at a high speed. SOLUTION: In the liquid delivering head, second holes 18, first holes 19 and a slit 20 are provided in the valve supporting member 11. The first holes 19 have their centers on straight lines LB3 to LBn-2 on the valve supporting member 11 and parallel to the arranging direction of a movable valve 6, and on straight lines LA1 to LAn parallel to the direction intersecting at right angles to the arranging direction of the movable valve 6, and are arranged zigzag. The second holes 18 have their centers on straight lines LB1, LB2, LBn-1 and LBn on the valve supporting member 11 and parallel to the arranging direction of the movable valve 6, and on straight lines LA1 to LAn parallel to the direction intersecting at right angles to the arranging direction of the movable valve 6, and are arranged zigzag.
