<p>PROBLEM TO BE SOLVED: To provide a liquid droplet discharge head which maintains a liquid supply function to an individual liquid chamber, and prevents reduction of liquid droplet discharge speed when a supply hole disposed on a liquid filter part is clogged with foreign matters without increasing thickness of the liquid filter part for partitioning a space of the individual liquid chamber side and a common liquid chamber.SOLUTION: A liquid supply part 111c has a cross section reduction area 111e whose cross section on a channel cross section orthogonal to a liquid supply direction going to an individual liquid chamber 111a from the liquid supply part 111c via a fluid resistance part 111b is smaller than a cross section on a channel cross section of the individual liquid chamber 111a, and is larger than a cross section on a channel cross section of the fluid resistance part 111b.</p> |
