The above desulfurizing agents are capable of adsorbing and removing with good efficiency the sulfur contained in hydrocarbons derived from petroleum to a content of 0.2 wt. ppm or less and have a long service life. The steam reforming of hydrocarbons derived from petroleum having been desulfurized by use of any one of the above desulfurizing agents allows the production of hydrogen for use in a fuel cell with good efficiency.

An optical fiber aligning member includes at least two grooved substrates, each of which has a first main surface in which optical fiber aligning grooves and at least two first positioning grooves are formed and a second main surface opposite the first main surface in which at least two second positioning grooves are formed. The grooved substrates are laminated on top of each other in a manner so that each grooved substrate is alternately turned over. First positioning pins are positioned in the first positioning grooves and second positioning pins are positioned in the second positioning grooves for aligning the alternating grooved substrates. In a method for making the optical fiber aligning member, the fiber aligning grooves and the positioning grooves are formed in the surfaces of a flat plate. The grooved substrates are formed by dividing the flat plate at an angle perpendicular to the grooves. The grooved substrates are stacked alternately so that grooved substrates that were adjacent each other in the flat plate are stacked adjacent each other in the optical fiber aligning member with their positioning grooves opposing each other.

When a resin 59 to form a molded body 20 is poured and a lead frame 30 is attached to a front end face 21 of the molded body 20 by insert molding, protective leads 32 provided on both outsides of a lead pattern 31 of the lead frame 30 moderate the flow of the resin 59 and the force acting on the lead pattern 31 is decreased, so that misregistration of the lead pattern 31 can be prevented. Accordingly, the inserted and molded lead frame 30 can be wired on the front end face 21 of the molded body 20 for easily accomplishing three-dimensional electric wiring.
