PROBLEM TO BE SOLVED: To provide a liquid jetting head in which breakage of a diaphragm caused by a stress of an adhesive for joining a substrate to a passage formation substrate is prevented, and to provide a liquid jetting apparatus. SOLUTION: A plurality of recesses 34 to be an escape of the adhesive are formed in the perimeter of a piezoelectric element holding part 31 at a joining face to the passage formation substrate 10 of a protecting substrate 30. Moreover, the recesses 34 are formed only at areas opposed to side walls 17 of feeding passages 15 in regions corresponding to the feeding passages 15. COPYRIGHT: (C)2007,JPO&INPIT
