1. A MEMS device comprising:

  • a protective substrate on which is mounted a driving circuit that drives a pressure generating unit and on which is formed an interconnect pattern electrically connected to the driving circuit; and

    a sealing substrate that includes an opening and that is bonded to the protective substrate using an adhesive so that part of the interconnect pattern is located between the protective substrate and the sealing substrate,wherein the interconnect pattern includes a connection portion that extends from a region where the protective substrate and the sealing substrate are bonded by the adhesive to the opening, and that has a connection region electrically connected to the driving circuit; and

    a groove is formed in the connection portion between the connection region and a border between the region and the connection portion.
