The present invention is a method for manufacturing an organic thin-film transistor substrate including an organic thin-film transistor as a transistor element, and an object of the invention is to provide a manufacturing method capable of forming a bank in a smaller number of steps. The method for manufacturing the organic thin-film transistor substrate of the present invention, in which an organic thin-film transistor is formed in a first region on a substrate, a second region for forming a light-emitting element in abutment with the first region is included, and a bank part is formed in a peripheral part of the second region, is characterized by including: a first step of forming the organic thin-film transistor in the first region on the substrate and forming at least one of the gate insulation layer and the organic semiconductor layer included by this organic thin-film transistor as far as the second region, thereby forming, in the second region, a bank precursor layer composed of a laminated structure formed on the second region; and a second step of removing the regions of the bank precursor layer other than the peripheral part, thereby forming the bank part made of the remaining bank precursor layer.

A constant-temperature type crystal oscillator includes: a crystal unit including a case main body including a first power source terminal on an outer bottom surface thereof; a surface-mounted oscillator; a temperature control circuit including a heating resistor and a temperature sensor; and a circuit substrate including a second power source terminal. One ends of the heating resistor and the temperature sensor are electrically connected to the second power source terminal. The first power source terminal of the surface-mounted oscillator and the one ends of the heating resistor and the temperature sensor are electrically connected to the second power source terminal of the circuit substrate. The first power source terminal of the surface-mounted oscillator is directly and electrically connected to, at least, the one end of the temperature sensor via an electrically-conducting path.
