PROBLEM TO BE SOLVED: To provide a fuel supply unit which improves workability and is capable of improving an effect of absorbing pulsation of a pressure that may be generated within an introduction passage during operation of an injector, and a manufacturing method of the fuel supply unit.SOLUTION: A hydrogen unit 24 comprises: an introduction block 40 including an introduction passage 52 for introducing a hydrogen gas; and at least one injector 42 connected to the introduction passage 52 for adjusting a flow rate and a pressure of the hydrogen gas. In the hydrogen supply unit, the pressure of the hydrogen gas is reduced by emitting the hydrogen gas that is introduced into the introduction passage 52, to the outside of the introduction passage 52 by the injector 42. The introduction passage 52 includes: a plurality of expansion chambers 56; a communication path 58 communicating the neighboring expansion chambers 56; and a fitting hole 60 which is communicated to the expansion chamber 56 and in which the injector 42 is disposed. The communication path 58 is formed coaxially with the fitting hole 60.SELECTED DRAWING: Figure 3 |
