Liquid ejecting head and liquid ejecting system with a sealing member

A liquid ejecting head comprising:

• a first flow path forming member including a first flow path which has a communication portion and which communicates with a nozzle opening;
• a sealing member which has a communication port and which seals an opening of the first flow path;
• and
• a second flow path forming member including a second flow path which has a communication portion and which supplies a liquid to the first flow path, the first flow path forming member, the sealing member, and the second flow path forming member being sequentially laminated,
• wherein
• the communication portion of the first flow path communicates with the communication portion of the second flow path via the communication port of the sealing member interposed therebetween,
• wherein
• the sealing member includes a diaphragm layer which forms one surface of the first flow path and a resin layer laminated on the diaphragm layer, and
• at least a part of an inside wall of the communication port is covered with a resin cover layer formed from a second resin different from a first resin which forms the resin layer, the resin cover layer is formed from an aminophenol-type epoxy resin-based adhesive.
