摘要： The optical communication device substrate according to the present invention includes one of ceramic and glass ceramic each having an average thermal expansion coefficient of −55 to −120×10−7/C° in the temperature range of −40 to +100 C° and each containing one of a β-quartz solid solution and a β-eucryptite solid solution as a main crystal. In the substrate, maximum thermal expansion hysteresis that occurs when temperature rise from −40 C° to 100 C° at a rate of 1 C°/min and temperature lowering from −100 C° to −40 C° at a rate of 1 C°/min are performed is less than 12 ppm.
