PROBLEM TO BE SOLVED: To provide a multi-needle sewing machine which can improve the efficiency in maintenance such as an exchange of a sewing needle and oil filling by balancing cumulative needles by needle bars. SOLUTION: In the multi-needle sewing machine, a controller acquires a needle number n required for the sewing of two or more partial patterns by such two or more partial patterns (step S23) and is organized so that needle numbers Nb1-Nb6 by such a needle bar are balanced among two or more needle bars and two or more top threads are allotted to two or more needle bars based on the acquired needle number n in order to decide a needle bar to serve to the sewing of partial patterns (step S24-S27).
