  Our concordance cosmological model predicts that galaxy clusters grow at the
intersection of filaments structuring the cosmic web stretching tens of Mega
parsecs. Although this hypothesis has been supported by the baryonic
components, no observational study has detected the dark matter component of
the intracluster filaments (ICFs), the terminal segment of the large-scale
cosmic filaments at their conjunction with individual clusters. We report
weak-lensing detection of ICFs in the Coma cluster field from the ~12 sq. deg
Hyper Suprime-Cam imaging data. The detection is based on two methods:
matched-filter technique and shear-peak statistic. The matched-filter technique
(shear-peak statistic) yields detection significances of 6.6- (3.1) $\sigma$
and 3.6- (2.8) $\sigma$ for the northern and western ICFs at 110$^{\circ}$ and
340$^{\circ}$, respectively. Both ICFs are highly correlated with the
overdensities in the WL mass reconstruction and are well-aligned with the known
large-scale ($>10$ Mpc) cosmic filaments comprising the Coma supercluster.
