Abstract: A multilayer ceramic capacitor includes a base body including dielectric ceramic layers and internal electrode layers stacked in a thickness direction, and a pair of external electrodes on first and second end surfaces and electrically connected to the internal electrode layers. The dielectric ceramic layers include, as a main component, crystal grains including a perovskite complex oxide including barium and titanium, and a rare earth element, and include, in a cross section including the thickness direction, a rare earth element high-concentration region in an area proportion of about 50% or more, the rare earth element high-concentration region including the rare earth element in a molar ratio of the rare earth element to titanium of about 0.04 or more and about 0.30 or less.

Abstract: A thermoplastic resin composition includes a graft copolymer (A) obtained by graft copolymerization of a monomer mixture (a) that includes at least an aromatic vinyl monomer (a1) and a (meth)acrylate monomer (a2), but does not practically contain a vinyl cyanide monomer (a3), in the presence of a rubbery polymer (r) having a refractive index of not lower than 1.510 and not higher than 1.520; and a vinyl copolymer (B). An acetone insoluble component (C) of the thermoplastic resin composition does not practically contain a vinyl cyanide monomer-derived unit. An acetone soluble component (D) of the thermoplastic resin composition contains the vinyl cyanide monomer-derived unit. The content of the vinyl cyanide monomer-derived unit is not lower than 2% by mass and not higher than 20% by mass relative to 100% by mass of the acetone soluble component (D).
