Superconducting nanostrip single photon detector (SNSPD) have attracted attention as detector with high detection efficiency in the mid-infrared wavelength region. A photon energy is smaller in the mid-infrared than in the near-infrared, so the detection sensitivity must be improved. In this study, we fabricated SNSPD consisting of thinner and narrower superconducting nanostrips than our previous SNSPD and evaluated the detection efficiency at wavelengths of 4.3 \micro m and 6.1 \micro m.
