PROBLEM TO BE SOLVED: To provide a forging punch, forging equipment, a micro forging method, a liquid jetting head manufacturing method which realize accurate formation of a partition of a recessed part and highly accurate working of a recessed shape for a pressure generating chamber and the like, and also to provide a liquid jetting head or the like obtained by the liquid jetting head manufacturing method. SOLUTION: The forging punch consists of a first and second dies 51a, 52a for forging metallic base stock plates 30, 55. In the first die 51a, there are installed projections 53 arrayed in parallel and voids 53b formed between the projections 53. In the second die 52a, recesses 54a are provided so that the height of the middle section is set low. By working using the punch, the base stock plates 30, 55 on both sides of the recess 54a are moved to the recess 54a, with the flow rate of the base stock plates to the voids 53b uniformized as much as possible. Consequently, the liquid jetting head 1 is given stability in its liquid jetting characteristic, enabling the manufacturing cost to be reduced through the simplification of working by forging.
