Zusammenfassung:	An intake apparatus of a diesel engine includes a plurality of intake ports (3,4) provided in each of cylinders. The respective intake ports (3,4) have throat portions (3a,4a) which extend straightly to a cylinder bore (2) of each of the cylinders. The respective intake ports (3,4) are provided to be directed to the tangential line of the cylinder on the surface orthogonal to a cylinder axial line (VR,VF) and to be directed in the same swirl flow directions. The intake ports (3,4) includes a front intake port (4) located at the front side in the swirl flow direction and a rear intake port (3) located at the rear side in the swirl flow direction. The front intake port (4) and the rear intake port (3) are provided so that velocity distribution of the intake air from the front intake port (4) is more directed to the swirl direction than that from the rear intake port (3).
