Since the portion is provided on the other side, a holder as a single body is not required. In addition, since both ends of the fluorescent lamp body and the lighting circuit structure can be inserted from the large-diameter opening end side of the case, complicated and cumbersome operations such as inverting the holder during assembly and joining the holder to the case are required. Becomes unnecessary. Further, the amount of expensive resin such as PBT resin used can be reduced.
