Abstract: A voltage is applied between a cylindrical cutting grindstone 2 that rotates about a vertical axis Y and a cylindrical truing grindstone 6 that rotates about a horizontal axis X. The vertical outer surface 2a and the horizontal lower surface 2b of the cutting grindstone are trued by a plasma discharge. Then without applying the voltage, the cutting grindstone 2 is trued mechanically by the truing grindstone 6, and while the outer periphery and lower surface of the cutting grindstone are dressed electrolytically, the outer periphery and lower surface are made to contact a workpiece 1 and process a micro-V groove. This method makes it possible to produce an immersion grating with a high resolution using hard, brittle materials such as germanium, gallium arsenide and lithium niobate.

A back body has lower portions (19a) of right and left edges that extend spreadingly downward from a vertical intermediate position. Seamlines between right and left edges of the front body and corresponding edges of the back body elongate from back waist portions to the hip hemlines with an outward detouring around the top of the buttock.
