To provide an article inspection apparatus capable of sensitively and stably detecting a change in a spectrum when an unspecified foreign substance is contained and determining a defective product. A transport unit that transports a tablet for inspection to an article inspection position, a light irradiation unit that irradiates the tablet transported to the article inspection position with light, a light detection unit that detects light transmitted through the tablet, and an article inspection unit that inspects a quality of the tablet based on spectral characteristics of the light detected by the light detection unit are provided, and the article inspection unit standardizes a measured value of a spectrum of the light detected by the light detection unit for each wavelength and determines whether the tablet is a normal product or a defective product based on a standardized value.

Article inspection apparatus using spectrum analyzer

An object is to provide a transmission line having an air bridge structure in which grounding conductors of a transmission line are connected by wiring and which is stable in terms of mechanical strength by lowering an electrostatic capacitance in a region where the wirings connecting the central conductor and the grounding conductor intersect with each other. The transmission line includes a substrate, a first central conductor and a second central conductor that are formed on a surface of the substrate, a third central conductor that has a first erection portion and a second erection portion erected on the surface, and a first grounding conductor and a second grounding conductor. The transmission line further includes a third grounding conductor connecting the first grounding conductor and the second grounding conductor. The third central conductor and the third grounding conductor form an air bridge structure.
