  The elastic electromagnetic form factors in the space-like region and valence
quark distribution functions for the K+ meson are calculated using the
confining Nambu-Jona-Lasinio model with the help of the proper-time
regularization scheme, which simulates quark confinement. In this model
framework, the dynamics information on the nonperturbative aspects is obtained
from quark propagators and bound state amplitudes via Bethe-Salpeter equations.
We found that the results on the kaon form factors and valence quark
distribution functions are qualitatively in excellent agreement with the
existing kaon data as well as the perturbation QCD prediction at higher $Q^2$.
