The application discloses a control method for continuous heat treatment equipment that can achieve good temperature uniformity in the width direction in total. The continuous heat treatment equipment 1 is provided with a first heating section, a second heating section and a third heating section, which are arranged along a conveyance direction F of a metal member, a control section that controls a first output power, a second output power and a third output power output to each of the first heating section, the second heating section and the third heating section, respectively, and a first measurement section that measures a first voltage and a first current in the first heating section. The first heating section, the second heating section and the third heating section are solenoidal induction heating, transverse induction heating and resistance heating, respectively. The control section rationally proportions the output share of each heating section, and also calculates a equivalent impedance in a parallel
