The Euclidean path-integral formula for linearized gravitational field is derived from canonical quantization in an "axial gauge". To make a path integral measure well-defined the system is put in a box after introducing a lattice, where gauge symmetry in the continuum must be modified with an appropriate replacement of differential operators. By inserting identities into a noninvariant path-integral formula, the gauge invariant expression is recovered. It is found that in order to get the Euclidean action one has to take the contours of integrations for h_<00>, as well as h_<0i>, along the imaginary axis. The former corresponds to conformal rotation proposed by Gibbons, Hawking and Perry, and the latter to the Wick rotation.
