<P>PROBLEM TO BE SOLVED: To provide a liquid ejecting head and a liquid ejecting apparatus in which members constituting liquid flow passages are reliably bonded to each other with adhesive and the quality of discharge is improved by increasing the discharging property of air bubbles in the liquid flow passages. <P>SOLUTION: A reinforcing member 48 and a vibration plate 51 include a first flow passage 71 and a communicating hole 78 respectively, each constituting a part of the liquid flow passages. An annular first protrusion 91 is arranged around the first flow passage 71 and an annular second protrusion 92 is arranged around the first protrusion 91. A gap G1 between a bonding plane 91a of the first protrusion 91 and the vibration plate 51 and a gap G2 between a bonding plane 92a of the second protrusion 92 and the vibration plate 51 are formed evenly. The adhesive 77 is provided up to the first flow passage 71 over the bonding plane 91a of the first protrusion 91 and up to the outside of the second protrusion 92 over the bonding plane 92a of the second protrusion 92. <P>COPYRIGHT: (C)2013,JPO&INPIT |
