  Intrinsic alignments (IA), the coherent alignment of intrinsic galaxy
orientations, can be a source of a systematic error of weak lensing surveys.
The redshift evolution of IA also contains information about the physics of
galaxy formation and evolution. This paper presents the first measurement of IA
at high redshift, $z\sim 1.4$, using the spectroscopic catalog of blue
star-forming galaxies of the FastSound redshift survey, with the galaxy shape
information from the Canada-Hawaii-France telescope lensing survey. The IA
signal is consistent with zero with power-law amplitudes fitted to the
projected correlation functions for density-shape and shape-shape correlation
components, $A_{\delta+}=-0.0071\pm 0.1340$ and $A_{++}=-0.0505\pm 0.0848$,
respectively. These results are consistent with those obtained from blue
galaxies at lower redshifts (e.g., $A_{\delta+}=0.0035_{-0.0389}^{+0.0387}$ and
$A_{++}=0.0045_{-0.0168}^{+0.0166}$ at $z=0.51$ from the WiggleZ survey). The
upper limit of the constrained IA amplitude corresponds to a few percent
contamination to the weak-lensing shear power spectrum, resulting in systematic
uncertainties on the cosmological parameter estimations by $-0.052<\Delta
\sigma_8<0.039$ and $-0.039<\Delta \Omega_m<0.030$.
