Liquid ejecting head, method of manufacturing the same, and liquid ejecting apparatus

A liquid ejecting head having an nozzle opening for ejecting liquid supplied from a liquid reservoir unit, which stores the liquid, through a liquid supply passage, comprising:

• a first supply member and a second supply member, each of which has the liquid supply passage formed therein;
• a filter that is held between the first supply member and the second supply member in correspondence with the liquid supply passage;
• a thermally welded portion that is welded to the filter so that the first supply member melts and soaks into the filter in a region that surrounds the liquid supply passage;
• a bonded portion at which the second supply member is bonded to the filter by the thermally welded portion;
• and
• a bonding resin that is formed by being poured into an outer region between the first supply member and the second supply member and outside the thermally welded portion and bonded portion with respect to the liquid supply passage.
