Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting head comprising:

• a head main body that has nozzles ejecting liquid droplets;
• and
• a flow passage member in which a liquid flow passage is formed, the liquid flow passage connecting a storage unit storing the liquid and the head main body,
• wherein the flow passage member includes a first member that configures a portion of a wall surface of the liquid flow passage, and a second member that configures a portion of a wall surface different from the first member of the liquid flow passage,
• wherein the first member and the second member are joined at a first joining region that surrounds a periphery of the liquid flow passage and a second joining region that is further to an outside of the flow passage member than the first joining region, wherein the second joining region has a gas barrier property higher than that of the first joining region,
• wherein a space is defined between the first joining region and the second joining region, wherein the space is separate from and fluidly isolated from the liquid flow passage,
• wherein the space communicates with the outside through a communication hole.
