The shake by mountain climibing influences the graviity measurement with CG-5 graviemeter. To investigate this influence, we conducted two investigations: the dynamic and the static disturbances. The dynamic disturbance means swing caused by walking, and the static disturbance means a tilt of the gravimeter with long time in carrying. In the investigation of the dynamic disturbance, measured gravity leaped negatively just after the climbing, but they did not correlate to times of climbing. In the investigation of the static disturbance, we found the correlation between leap values of gravity and duration times of tilt in the case of tilt angle greater than 5.0 degree.
