There is provided a scanning electron microscope capable of achieving a size reduction of the device while at the same time suppressing the increase in column temperature as well as maintaining performance, e.g., resolution, etc. With respect to a scanning electron microscope for observing a sample by irradiating the sample with an electron beam emitted from an electron source and focused by condenser lenses, and detecting secondary electrons from the sample, the condenser lenses comprise both an electromagnetic coil-type condenser lens and a permanent magnet-type condenser lens.
