摘要： A pressurizing chamber 1 is formed as a recess by half etching of a silicon single-crystal substrate 2. A nozzle communicating hole 6 through which the pressurizing chamber 1 is connected to a nozzle opening 5 is formed as a through hole which is smaller in width than the pressurizing chamber 1. The pressurizing chamber 1 is connected to the nozzle opening 5 in the other face via the nozzle communicating hole 6 while reducing the volume of the pressurizing chamber 1 to a degree as small as possible. The silicon single-crystal substrate is used as a member constituting a spacer so that an ink drop of a reduced ink amount suitable for high density printing flies with high positioning accuracy.
