Relative resolving power of electron microscope using Ag, Cu, brass, Al etc. for slit material of objective electron-lens was determined from degree of roundness of corners of MgO crystal. Each slit was 9/100 mm thick and 1/10 mm dia.<BR>It was found that (i) Ag slit had the best resolving power (ii) lowering of resolving power due to contamination of a slit was mainly attributed to the disturbance of electrostatic field by charge up of electrons, and also (iii) Au slit was the most suitable one for continuous working of electron-microscope.
