  Fine-grained nuclear emulsion films have been developed as a tracking
detector with nanometric spatial resolution to be used in direction-sensitive
dark matter searches, thanks to novel readout technologies capable of
exploiting this unprecedented resolution. Emulsion detectors are time
insensitive. Therefore, a directional dark matter search with such detector
requires the use of an equatorial telescope to absorb the Earth rotation
effect. We have conducted for the first time a directional dark matter search
in an unshielded location, at the sea level, by keeping an emulsion detector
exposed for 39 days on an equatorial telescope mount. The observed angular
distribution of the data collected during an exposure equivalent to 0.59 g days
agrees with the background model and an exclusion plot was then derived in the
dark matter mass and cross-section plane: cross-sections higher than $1.3
\times 10^{-28}$ cm$^{2}$ and $1.7 \times 10^{-31}$ cm$^2$ were excluded for a
dark matter mass of $10$ GeV$/c^2$ and $100$ GeV$/c^2$, respectively. This is
the first direction sensitive search for dark matter with a solid-state,
particle tracking detector.
