るからである。However, when the dipping method is applied, a method of immersing in a dipping liquid to form a coating film on the outer surface of the arc tube is usually adopted with the other end of the arc tube where the remaining portion of the exhaust tube is located at the top. You. This is for the following reason. In other words, when dipping liquid is immersed in the dipping liquid with the one end where the pinch seal portion of the arc tube is located at the top, the dipping liquid adheres to the lead rod protruding from the pinch seal part. Is required to be masked beforehand, which complicates the manufacturing process.
