Abstract
To provide a bulb-type lamp in which a globe is fixed to a case without a tilt, and a manufacturing method for the bulb-type lamp. The globe is bonded to a connector using a thermosetting resin, in a state where a neck part of the globe is inserted in a groove of the connector without contacting the bottom of the groove. The connector is then fixed to the case by means of a fitting construction. This makes it unnecessary to perform a heating process to cure an adhesive after an envelope is formed by the globe and the case. Hence the tilting of the globe caused by the thermal expansion of air in the envelope can be prevented.
