A startup control method of a resin extruder is provided. The resin extruder extrudes supplied resin material to a die as molten resin by rotating a screw. The resin material is supplied with a low supply amount which is smaller than a target supply amount and the screw is rotated at a low rotational frequency which is smaller than a target rotational frequency when starting the resin extruder. A supply amount of the resin material and a rotational frequency of the screw are gradually increased. After elapse of a set startup time, the supply amount of the resin material is brought into a target supply amount and the rotational frequency of the screw is brought into a target rotational frequency.
