An object is to extend the life of the target member. The target (TA2) is designed to have a symmetrical structure so as to realize an invertible configuration. According to this, even if the consumption of the target member (71) is large on the side closer to the plasma generation unit where the plasma density is high, the portion of the target member (71) which has been located on the side closer to the film formation object where the plasma density is low and is thus consumed less can be rearranged on the side closer to the plasma generation unit where the plasma density is high, by inverting the target (TA2).
