1. An apparatus comprising:
- a transmission line including a substrate and a conductor provided on the substrate;
an electromagnetic-wave supplying unit for supplying an electromagnetic wave in a frequency range between 30 GHz and 30 THz to the transmission line;
an electromagnetic-wave detecting unit for detecting the electromagnetic wave transmitted through the transmission line; and
an infiltrative holding member provided on the conductor for infiltration and holding of a liquid object,wherein a shape of the infiltrative holding member is asymmetrical with respect to the conductor and the infiltrative holding member is disposed such that an electric field distribution of the electromagnetic wave transmitted through the transmission line is substantially symmetrical with respect to the conductor.

Abstract
A detecting apparatus for detecting information of a liquid object or sample includes a transmission path, a THz wave supplying unit, a THz wave detecting unit, and an infiltrative holding member for infiltration and holding of a liquid object. The supplying unit supplies an electromagnetic wave in a frequency range between 30 GHz and 30 THz to the transmission path. The detecting unit detects the THz wave transmitted through the transmission path. The infiltrative holding member is set at a location containing at least a portion in which an electric field distribution of the THz wave propagating along the transmission path extends.
