Abstract:
1. A probe apparatus that provides an electrical connection between a device under test and a test apparatus body, comprising: a device-side terminal unit that includes a flexible sheet and a plurality of device-side connection terminals passing through the sheet and connected to the device under test; an intermediate substrate that is provided on the test apparatus body side of the device-side terminal unit and includes a plurality of device-side intermediate electrodes electrically connected to the device-side connection terminals and a plurality of tester-side intermediate electrodes electrically connected to the test apparatus body, the tester-side intermediate electrodes of the intermediate substrate provided at intervals greater than intervals at which the device-side intermediate electrodes are provided, the intermediate substrate including: an anisotropic conductive film that is arranged between the device-side terminal unit and the intermediate substrate and provides a connection between the device-side connection terminals and the device-side intermediate electrodes; a tester-side substrate that is provided on the test apparatus body side of the intermediate substrate and includes, on the intermediate substrate side thereof, a plurality of tester-side electrodes electrically connected to the test apparatus body; and a contact section that is provided between the intermediate substrate and the tester-side substrate and includes a plurality of contact blocks, each contact block connected to a corresponding connection module of the plurality of connection modules, each contact block including
