Abstract
The purpose of the present invention is to provide a molded body that is for use as a housing and transmits electromagnetic waves such as millimeter waves but is still very dark black, a resin composition that is for use in forming the molded body for a housing and has favorable molding fluidity, and a masterbatch. This molded body for a housing is formed from a resin composition that includes a thermoplastic resin (A) and carbon nanotubes (B). The carbon nanotubes (B) have a specific surface oxygen concentration, diffraction peak half width, and Raman spectrum G/D ratio, the molded body includes 0.10-2 parts by mass of the carbon nanotubes (B) per 100 parts by mass of the thermoplastic resin (A), and the surface resistivity of the molded body is at least 1.0×10Ω/□.
