PROBLEM TO BE SOLVED: To prevent reduction in grain recovery efficiency caused by double reaping of crop grain culms. SOLUTION: The reaping and conveying structure of a combine harvester is equipped with a reaping and conveying part 3 provided with a pair of right and left raising frames 26A and 26B and a reaping apparatus 23 and a boarding operation part 2 right and left in parallel. The right and left raising frames 26A and 26B are provided with raking and conveying apparatuses 24A and 24B for conveying reaped crop grain culms to a grain culm passage part 27 formed between the right and left raising frames and the reaping and conveying part 3 is equipped with a supplying and conveying apparatus 25 for conveying reaped grain culms of the grain culm passage part 27 to a threshing apparatus 4. Inclination angles θa and θb between body longitudinal direction and body right and left direction of straight conveying paths 114A and 114B of the raking and conveying apparatuses 24A and 24B are set equal or approximately equal and an included angle θA between the straight conveying paths 114A and 114B in the right and left raking and conveying apparatuses 24A and 24B is set larger than an included angle θB between the straight conveying path 114A of the raking and conveying apparatus 24A at a side separating from the boarding operation part 2 and a straight conveying path 115 of the supplying and conveying apparatus 25.
