There is provided an external casing vertically arranged in a fuel tank of vehicles or like, in order to detect a linear electric signal of change in the height of fuel surface in the fuel tank and a slender metallic resistance body (10) is set along the axial line of an external casing (3). The resistance body (10) has a resistance circuit pattern (10A, 16, 26) formed at least at one surface thereof through the interposition of an electric insulating layer (15, 24), the resistance circuit pattern (10A, 16, 26) having a shape corresponding to that of the fuel tank. The lower end of the resistance body (10) is caused to project from the bottom of the external casing (3) so that the resistance body can be arranged vertically while being pulled in the direction of bottom of the external casing by means of a metal fitting (12, 13) provided at the projecting portion of resistance body.

A lighting unit, e.g. an LED bulb or a straight LED luminaire, which illuminates a wide range and is configured with low cost. In a light-emitting diode lamp, a board assembly is disposed in a lamp main body, and light-emitting diodes are attached to the board assembly. The board assembly comprises a plurality of flexible printed circuit boards. Each flexible printed circuit board includes a base in the form of a flat plate, respective connections to a power supply portion of the light-emitting diode lamp are provided at two ends of the base, and the base is bent at a plurality of points of a middle portion to form a top surface portion and side surface portions. The flexible printed circuit boards are three-dimensionally assembled such that the top surface portions cross each other and such that one of the top surface portions lies on top of another.
