A plasma CVD film formation apparatus includes: a reaction chamber; a shower plate installed inside the reaction chamber; and a susceptor for placing a wafer thereon installed substantially parallel to and facing the shower plate. The shower plate has a surface facing the susceptor, which is configured using a convex shape toward a center as a basic shape and overlaying at least one equation thereon, and the susceptor supports the wafer at a peripheral portion and at a position between a central portion and the peripheral portion.
