There are disclosed a scanning probe microscope and scanning method capable of reducing or avoiding damage due to collision between a probe tip and a sample, shortening the measuring time, improving the throughput and measuring accuracy, and collecting observational data such as topographic data about the sample surface without being affected by an adhesive water layer. The microscope has a vibration unit for vibrating the probe tip, an observation unit for collecting observational data when the tip is in proximity or contact with the sample surface, a detector for detecting a variation in the state of vibration of the tip when it is in proximity or contact with the sample surface, and a control unit for controlling movement of the tip in X- and Y-directions parallel to the sample surface and in a Z-direction vertical to the sample surface. After collecting the observational data, the control unit scans the tip in a direction parallel to the sample surface until a next observation position in the X- or Y-direction is reached. During the scanning, if a variation in the state of vibration of the tip is detected, the control unit moves the tip in the Z-direction away from the sample surface.
