A sandwich maker includes a lower baking plate, a baking ring, an upper baking plate, a partition, and a heat insulation ring. The partition can be pulled out through a handle to separate the partition together with the heat insulation ring from the baking ring, so that the interiors of the lower baking plate, the baking ring and the upper baking plate communicate with each other. The sandwich maker can separate the ingredients for cooking and can directly assemble the ingredients to form a sandwich. The removed partition can be easily placed through the heat insulation ring without worrying that the partition may damage a tabletop.
