发明名称 INSPECTION MASTER BLOCK AND METHOD OF PRODUCING THE SAME
摘要 A plurality of fixing holes (13) are made in the upper and side faces of a hollow rectangular prism block body (1A) at least the top and four side face s of which are quartz glass or monocrystalline quartz rectangular plates (10, 11, 12). A plurality of reference members (9), each having a reference measuring face with which the fore end of a probe of a measuring apparatus i s brought into contact, are inserted into the fixing holes (13), respectively, and secured in place. An inspection master block ensuring a high inspection accuracy by minimizing the effect of ambient temperature variation and a method for producing the same are thereby provided.
