Abstract: We present the SPICA Coronagraph Instrument for the direct imaging and spectroscopy of exoplanets. The SPICA mission gives us a unique opportunity for high-contrast observations because of the large telescope aperture, the simple pupil shape, and the capability for infrared observations from space. The primary goal of this coronagraph is the direct detection and spectroscopy of Jovian exoplanets. The specifications, performance, and the design of the instrument are shown. The main wavelengths and the contrast required for the observations are 3.5 – 27μm, and 10–6, respectively. We also show the progress of the development of key technology to realize this instrument. The non-coronagraphic mode of this instrument is potentially useful for characterization of inner planets via observation of planetary transit and Color Differential Astrometry (CDA). We expect the SPICA coronagraph will provide drastic progress for understanding various planetary systems by it’s unique capability, and will be a fruitful precursor for a future mission targeting terrestrial planets.
