Environmental test equipment, test specimen evaluation method, and test equipment

摘要

The present invention provides an evaluating substrate that is capable of accurately evaluating temperature characteristics of a test specimen because test temperature irregularities are unlikely to occur even in case a test specimen like a self-heating one is tested. According to the present invention, the test specimen (10) is evaluated by exposing the test specimen (10) to a desire temperature while the test specimen (10) is energized. The present invention includes a substrate main body (2) that has a wide surface shape; a mounting portion (3) on which the test specimen (10) can be mounted; and a heater (8) that heats the substrate main body (2). The mounting portion (3) is positioned on one circumferential surface of the substrate main body (2) and the heater (8) is distributed in the shape of a plane on the other circumferential surface of the substrate main body (2) and is integrated thereto.
