PROBLEM TO BE SOLVED: To provide a liquid droplet discharge head improved in handling performance by increasing rigidity of common supply flow path forming members and having high operating reliability with stabilized discharge characteristics.SOLUTION: A liquid droplet discharge head includes a plurality of nozzles 1 arranged like a row, a pressure chamber 3 communicated to each nozzle 1 individually, a pressure generating means 17 for giving the change of pressure to the pressure chamber 3, an individual supply flow path 4 communicated to the pressure chamber 3 individually, and a common supply flow path forming member 10 formed with a common supply flow path 8 communicated to the individual supply flow path 4. A filter 7 is provided in the common supply flow path 8. The common supply flow path 8 is divided into an upstream side common supply flow path 8a and a downstream side supply flow path 8b across the filter 7. An upstream side grating part 9a and a downstream side grating part 9b are formed in the upstream side common supply flow path 8a and the downstream side supply flow path 8b, respectively. |
