Abstract: PURPOSE:To detect an absolute value of an offset of a lead and a sinking and levitating state of the lead and to accurately inspect whether a defect exists or not by a method wherein a reference mark is formed on the scanning line of light for inspection use on an IC stage. CONSTITUTION:The surface part of an IC stage 7 is constituted of a transparent sheet 8; reference marks 9, 9... composed of aluminum whose thickness is, e.g. about several hundred Angstrom  are formed on the surface of the transparent sheet 8. The reference marks are arranged on the scanning line on which a laser beam for inspection use is scanned; the reference marks are scanned together with leads 6, 6... by using the laser beam at an inspection operation. A QFPIC 5 under inspection is placed on the IC stage 7 in a prescribed plane positional relationship with reference to the reference marks 9, 9...; absolute plane positions of individual leads can be detected by making use of the reference marks as the origin.
