Wiring board for electronic parts inspecting device and its manufacturing method

A wiring board for an electronic parts inspecting device that can be designed and produced relatively quickly, inexpensively, and with a few number of jigs is provided. In certain embodiments the wiring board comprises a board main body having a front surface, a probe pad area having probe pads located in a central portion of the front surface, an outer connecting terminal area having outer connecting terminals located in a peripheral portion of the front surface, and wherein probe pads are connected to outer connecting terminals by front surface wirings formed between the probe pad area and the outer connecting terminal area. While certain embodiments further comprise inner wirings and first via conductors to connect the probe pads and outer connecting terminals, it is preferable to have no or a minimal amount of such inner wirings. Lastly, a method of manufacturing the same is provided.
