A productivity of a throttle body is improved by extremely easy fuel drawing in a first fuel distribution pipe holding a first fuel injection valve to one side wall of a first air intake passage, and a second fuel distribution pipe holding a second fuel injection valve to the other side wall of a second air intake passage. A first fuel distribution pipe (10) is provided with a first distribution tube portion (10a) in which a first fuel distribution path (10b) is provided, a first injection valve insertion tube portion (10d) having a first injection valve insertion hole (10g), and a first connection tube portion (10h) which is orthogonal to the first distribution tube portion (10a) and in which a first connection hole (10l) connected to the first fuel distribution path (10b) is provided. A second fuel distribution pipe (20) is provided with a second distribution tube portion (20a) in which a second fuel distribution path (20b) is provided, a second injection valve insertion tube portion (20d) having a second injection valve insertion hole (20g), and a second connection tube portion (20h) which is orthogonal to the second distribution tube portion (20a) and in which a second connection hole (20m) is provided.
