We have proposed using nano-antennas with superconducting detector to improve the response performance of infrared detectors. We have fabricated prototype of mid-infrared superconducting photo-detectors with twin-slot antenna. By the irradiation of mid-infrared (λ=4.9 μm) light, the responses with high polarization dependencies caused by antenna effect were observed. The response time was also evaluated, and it was about 0.3 nsec..
