Application of a clover Ge detector to the measurement of the linear polarization of $\beta$-delayed $\gamma$ rays was investigated. The spectrometer consists of the clover and coaxial-type Ge detectors, and will be installed at an on-line isotope separator to measure short-lived nuclei. To evaluate the performance of the spectrometer, the polarization sensitivities were determined using standard radioactive sources in various detector arrangements. During optimization of the detector setup, the figure of merit was found to depend on the solid angles subtended by the detectors.
