  We study the inflationary model constructed from a Spatially Covariant
Gravity (SCG). The Lagrangian for the SCG in our consideration is expressed as
the polynomial of irreducible SCG monomials where the total number of
derivatives of each monomial is two, and the theory propagates two tensorial
degrees of freedom of gravity up to the first order in cosmological
perturbations. The condition for having two tensorial degrees of freedom
studied earlier in literature for such theories is derived in vacuum. We extend
the condition for having two tensorial degrees of freedom to the case where a
scalar field is included by imposing a gauge-fixing. We apply the resulting SCG
to describe inflationary universe. The observational predictions such as the
scalar spectral index and tensor-to-scalar ratio from this model are
investigated. We find that the tensor-to-scalar ratio in this model can either
be in the order of unity or be small depending on the parameter of the model.
