<P>PROBLEM TO BE SOLVED: To realize an excellent condensing characteristic by which a phenomenon such as the total reflection of incident light is not caused in a microlens. <P>SOLUTION: The outside shape of the microlens is made by forming a hole 602 whose size is small, whose depth is large and which is a recessed part on a base plate 10. Then, a hole 601 whose size is large, whose depth is small and that is a slope part 603 having inclination smaller than an inclination to the surface of the base plate 10 that the hole 602 has near a boundary at which the surface of the base plate 10 and the hole 602 come into contact is inserted into the boundary. <P>COPYRIGHT: (C)2003,JPO |
