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: The present invention relates to a toner binder containing: a polyester resin (A); and a vinyl resin (B), wherein the polyester resin (A) is a resin obtained by crosslinking a polyester (A1) by one or more carbon-carbon bonds, the vinyl resin (B) is a polymer containing a monomer (a) as an essential constituent monomer, the monomer (a) is a C21-C40 (meth)acrylate having an acyclic hydrocarbon group, and the weight proportion of the monomer (a) in monomers constituting the vinyl resin (B) is 15 to 99% by weight based on the weight of the vinyl resin (B).
