摘要： A charged particle generator includes a first electrode, a second electrode, and an insulating material that is provided between the first electrode and the second electrode. The second electrode has an opening that opens in a first direction in which the first electrode, the insulating material, and the second electrode are arranged. The insulating material has a region limiting space. The region limiting space corresponds to the opening. The region limiting space is continuous with the opening. The region limiting space is a space that opens in a direction in which the region limiting space is oriented toward the opening and that is limited in a second direction perpendicular to the first direction. The first electrode has an anisotropic resistance portion in which a resistance component in the first direction is smaller than a resistance component in the second direction.
