An IC handler () of the present invention transfers an IC device (D) to a test head (). The test head () is provided with a socket (), which has a placing surface () having the IC device (D) placed thereon, and which attaches the IC device (D) placed on the placing surface () to the test head (). The IC handler () is provided with a non-contact displacement meter () that is disposed by being spaced apart from the socket () in the direction perpendicular to the placing surface (). The non-contact displacement meter () measures a distance from the non-contact displacement meter () to the IC device (D) placed on the placing surface () by emitting a laser beam toward the placing surface () of the socket ().
