An EGR device is operated and EGR is executed, when a temperature of a first cooling water that cools a cylinder block and a cylinder head is higher than an EGR allowable temperature, and a working point of the internal combustion engine that is fixed by a load and an engine speed is in an EGR execution region. The EGR execution region is variable with respect to a temperature of the second cooling water (the temperature of the second cooling water is lower than the first cooling water) that cools the intake port, and the EGR execution region is narrowed to a high load side in a case where the temperature of the second cooling water is lower than a threshold value temperature, as compared with a case where the temperature of the second cooling water is higher than the threshold value temperature.
