Since the styrene copolymer is not included, the heat resistance is low, and in Comparative Example 2, the amount of the maleimide-styrene copolymer added is too large, so the fluidity properties are poor. Furthermore, in Comparative Example 3, the flow characteristics were extremely poor because no aromatic polycarbonate was added.
