The present invention relates to a terahertz sensor chip including a split ring resonator and an apparatus for analyzing a terahertz sample using the same. The apparatus for analyzing a terahertz sample according to the present invention includes: a dielectric substrate generating a terahertz wave when a laser beam is irradiated; a first metal ring pattern and a second metal ring pattern provided on a surface of the dielectric substrate; a reference sample reservoir provided on a surface of the dielectric substrate inside the first metal ring pattern and into which a reference sample is injected; and a terahertz sensor chip provided on a surface of the dielectric substrate inside the second metal ring pattern and including an analysis target sample storage unit into which the analysis target sample is injected; a laser beam generator that generates a laser beam that excites terahertz waves; The laser beam generated by the laser beam generator is divided into a first laser beam irradiated to the reference sample reservoir and a second laser beam irradiated to the analysis target sample reservoir, and the first laser beam and the second laser an optical system for exciting a first terahertz wave and a second terahertz wave by irradiating a beam to the reference sample reservoir and the analyte sample reservoir, respectively; A reference sample signal is generated from the first terahertz wave passing through the reference sample in the reference sample reservoir, and an analysis sample signal is generated from the second terahertz wave passing through the analyte sample in the analysis target sample reservoir a detection unit; and a controller that controls the laser beam generator and the optical system, and compares the reference sample signal with the analysis sample signal.
