  Recently, the degenerate gamma functions are introduced as a degenerate
version of the usual gamma function by Kim-Kim. In this paper, we investigate
several properties of them. Namely, we obtain an analytic continuation as a
meromorphic function on the whole complex plane,the difference formula, the
values at positive integers, some expressions following from the Weierstrass
and Euler formulas for the usual gamma function and an integral representation
as the integral along a Hankel contour.
