<P>PROBLEM TO BE SOLVED: To provide a contention analysis device, a contention analysis method, and a program, which are suitable for analyzing whether the state of access contention for a shared resource is normal or not. Ž<P>SOLUTION: Control units 110A-110N execute an analysis target program including an instruction for exclusively making access to a shared resource. Meanwhile, the control unit 110X acquires an access right (lock) for the shared resource accessed by the analysis target program, and measures a lock acquisition required time required for acquiring the lock. Further, the control unit 110X stores nearest preceding lock acquisition required time by a predetermined number, and on the basis of the stored lock acquisition required time, calculates an allowable range for allowing as the lock acquisition required time. If a latest lock acquisition required time is within the allowable range, the control unit 110X analyzes the state of access contention for a shared resource as being normal.
