PROBLEM TO BE SOLVED: To provide a bus device performing bus transfer independently of operation of bus masters to efficiently use a bus line. SOLUTION: This bus device 1 has: a request queue 4 simultaneously holding request data threads from the plurality of bus masters 2m0 to 2mX; a request data thread selection device 5 selecting the request data thread held in the request queue 4, and transferring it by the bus line 6; and a request data thread distribution device 7 outputting the request data thread to a bus slave corresponding to a thread ID included in the request data thread transferred via the bus line 6. Requests from the bus masters 2m0 to 2mX is handled thereby by a unit that is the request data thread, the bus transfer is performed independently of the operation of the bus masters 2m0 to 2mX, and the bus line 6 is efficiently used.
