  We establish a new transcendence criterion of $p$-adic continued fractions
which are called Ruban continued fractions. By this result, we give explicit
transcendental Ruban continued fractions with bounded $p$-adic absolute value
of partial quotients. This is $p$-adic analogy of Baker's result. We also prove
that $p$-adic analogy of Lagrange Theorem for Ruban continued fractions is not
true.
