Each end is covered 3 to 7 mm. If it is smaller than 3 mm, the non-erosion area A2 of the targets 132a to 132d cannot be covered. On the other hand, if it is larger than 7 mm, the target 132a to 132d is larger than the reference non-erosion area, and the targets 132a to 132d are eroded. This is because the area is covered and the use efficiency of the targets 132a to 132d is low, and desired film formation characteristics cannot be obtained.

If the distance is less than 2 mm, the non-adherent particles are too close to each other, and the flange portion 22 and the targets 132a to 132d are connected to each other, which may cause a short circuit.
- the distance between the lower surface of the flange portion 22 and the targets 132a to 132d is too large, so that non-adherent particles do not adhere to the shield member 20, and adhere to the non-erosion region A2 of the targets 132a to 132d. End up. In this embodiment, it is 10 mm.
- a support member 23 is provided behind the backing plates 131a to 131d.
- the support member 23 includes a plate-like portion 231 and a protrusion 232 that extends at the center of the plate-like portion 231 in the width direction so as to be disposed between the backing plates 131a to 131d.

- FIG. Here, only the vicinity of the targets 41a and 41b is shown for explanation.
- the non-adhesion. Particles are unlikely to adhere to the non-erosion region A2 (see FIG. 3). This is because the end portion where non-adherent particles are likely to adhere is a tapered surface, so that the plasma also flows to the lower surface side of the flange portion 22, so that the non-erosion region A2 can be formed even narrower than in the first embodiment.
- the number of non-adhering particles adhering to the non-erosion region A2 can be further reduced.
- non-adherent particles are less likely to adhere to the non-erosion region A2. Further, since the distance between the targets 41a and 41b and the flange portion 22 of the shield member 20 in the sputtering apparatus 2 is increased, non-adherent particles form a film, and the targets 41a and 41b and the flange portion 22 of the shield member 20 are electrically connected. It is possible to suppress a short circuit due to the connection. If the height of the shield member 20 is increased in order to increase the distance between the targets 41a and 41b and the flange portion 22 of the shield member 20 in order to prevent a short circuit, non-adherent particles adhere to the non-erosion region A2.
