PURPOSE:To prevent run off of an external lead when brought into contact with a contact while enabling a long-life test, by pressing the external lead on the contact with a comb-shaped insulation leak keep plate to perform a test. CONSTITUTION:A ZIP type IC1 conveyed being guided on a guide groove 3a of a guide rail 3 is put between the guide groove 3a and a guide groove 4a at a testing position with an opposed rail 4 lowering in the direction 7. Then, leads 1a of the ZIP type IC1 are inserted into cuts 6a and 6b with a lead keep plate 6 lowering in the direction 8 to be insulated. Moreover, with the lead keep plate 6 lowering in the direction 9 as a whole, the guide rail 3 and the opposed rail 4, the ZIP type IC1 is tested as fixed by pressing the undersurface of the external leads 1a on a contact 5 one piece at a time.
