Abstract: A solid-state imaging device package comprises a solid-state imaging device including a functional portion that performs imaging at the center portion of a surface, a frame provided to surround the functional portion at the outer peripheral portion of the solid-state imaging device, and a transparent substrate that is opposite to the functional portion and fixed to the frame to cover the solid-state imaging device. A manufacturing method includes the steps of forming the frame by laminating a resin in multiple layers by a 3D printer on either one of the solid-state imaging device or the transparent substrate, and bonding one other of the solid-state imaging device or the transparent substrate to the frame. The step of forming the frame further includes laminating the resin so that a surface roughness Ra of an inner peripheral surface of the frame is 50 nm or more and 30 ?m or less.

Abstract: There has been a problem that wrinkles easily occur on a carbonaceous film produced by the use of a continuous production method and on a graphite film obtained by heat-treating the carbonaceous film. In the present invention, heating treatment is carried out on a polymeric film while applying pressure to the polymeric film in the film thickness direction with the use of a continuous carbonization apparatus. This makes it possible to obtain a carbonaceous film and a graphite film in which wrinkling is reduced.
