<p>PROBLEM TO BE SOLVED: To provide a reflective sensor of such structure that the breaking of a wire is hard to occur by the heat at mounting on the face by the method of hand reflow, though it can be manufactured by the same manufacture method as in the past. SOLUTION: This sensor 1 is a reflective sensor where a light emitting element 31 and a light receiving element 32, which are a specified interval apart from each other in plan view, are buried within a resin package 2 equipped with a top part, a bottom part, and a side part, and besides a part of each of the lead 5 electrically continuous to the light emitting element 31 and the lead 5 electrically continuous to the light receiving element 32 is arranged in the same level position as the level position of the bottom part of the resin package 2 or in roughly the same level position as it. Here, the resin package 2 is made, being equipped with the first transparent resin part 21 having the light emitting element 31 within, the second transparent resin part 22 having the light receiving element within, and an opaque shell resin part 25 which stops the area between the first transparent resin part 21 and the second transparent resin part 22, and besides covers the sides of the first transparent resin part 21 and the second transparent resin part 22, and besides each transparent resin part 21 and 22 is exposed to both of the top part and the bottom part of the resin part 2.</p> |
