A wiring board includes a dielectric substrate, a signal transmission line formed on one surface of the dielectric substrate, a grounded layer formed on the other surface of the dielectric substrate, and a connection portion for connecting portion for connecting the signal transmission line to a waveguide, the connection portion being formed on the grounded layer. Devices of the invention provide users with detailed information related to the pharmacodynamic behavior of insulin in a patient. The waterproof cover covers the dielectric and contacts to a portion of the surface of the dielectric.
