PURPOSE:To reduce a testing time, by providing a contact operation detecting part which outputs an inter-contact closeout signal representing the closeout of contacts of depressed plural pieces of push botton switches to be tested, and performing a simultaneous test for plural pieces of push button switches to be tested. CONSTITUTION:A depressing mechanism 51 which outputs a depressing force signal corresponding to the depressing force of respective push button which to be tested, and outputs a depressing distance signal corresponding to a depressed distance, when plural pieces of push button switches 12 to be tested are depressed simultaneously, and a contact operation detecting part 52 which outputs the intercontact closeout signal representing that the contacts of the plural pieces of push button switches 12 are closed out respectively, are provided. By using such keyboard testing device, it is possible to test the plural pieces of push button switches simultaneously, and to realize the remarkable reduction of a time required for the test of a keyboard.
