PROBLEM TO BE SOLVED: To protect a supply pipe supplying lubricating oil to a supercharger and reduce influence of radiation heat from a turbine chamber to the supply pipe. SOLUTION: In an engine with the supercharger, a supply part 1a of a cylinder block 1 having one end part of a supply pipe 43a supplying lubricating oil to the supercharger 4 connected thereon is provided in a compressor chamber 42 side of a bearing part 43 of the supercharger 4. Also, the supply pipe 43a is connected to an upper part of the bearing part from the supply part 1a through a gap between the cylinder block 1 and the supercharger 4, and more than half of the same is positioned in a supercharger 4 side of a virtual line L connecting an outer edge of a cylinder block 1 side of the turbine chamber 1 and an outer edge of a cylinder block 1 side of the compressor chamber 42 in a plane view.
