This invention is to improve the reaction efficiency of a peroxide introduced into a cylinder compared with conventional art. In the peroxide reaction method and peroxide reaction device using an extruder according to this invention, in which a peroxide (50 or 50A) and a raw material (20) such as a synthetic resin, a natural resin, and an elastomer are introduced into a cylinder (1) of the extruder (2), wherein the raw material (20) and the peroxide (50 or 50A) are reacted with each other in the cylinder (1), the raw material (20) is introduced from a raw material supply hopper (30), the peroxide (50 or 50A) is introduced from a downstream side of the raw material supply hopper (30), and the temperature of the raw material (20) in a peroxide introduction portion (31A, 32A, 33A) is adjusted to a temperature lower than the one-minute half-life temperature of the peroxide (50 or 50A).
