Proposed are an electrostatic chuck mechanism and a charged particle beam apparatus including a first plane that is a plane of a side in which a sample is adsorbed, a first electrode to which a voltage for generating an adsorptive power between the first plane and the sample is applied, and a second electrode that is arranged in a position relatively separated from the sample toward the first plane and through which a virtual line that is perpendicular to the first plane and contacts an edge of the sample passes, wherein the first plane is formed so that a size in a plane direction of the first plane is smaller than that of the sample.
