The invention provides a plastic package chip and a manufacturing method of the plastic package chip. The plastic package chip comprises a plastic package material (11) and heat radiation fins (12), wherein a containing groove (111) is arranged on the edge of the plastic package material (11); and the containing groove (111) is used for containing the heat radiation fins (12). With the adoption of the plastic package chip, the problem that the heat radiation fins occupy a larger chip space, so that the heat radiation effect of a plastic package chip is affected is realized; and the plastic package chip is simple and reliable in structure, easy to realize and has chip space conservation under the condition that a good heat radiation effect of the chip is ensured.
