摘要： An optical element having an antireflection effect includes an incident plane and an emission plane and a conical microstructure formed on at least one plane of the incident plane and the emission plane. The conical microstructure includes a first structure formed of a plurality of conical microprojections with an average height H1 and a second structure formed of a plurality of conical microrecesses with an average height H2. The average height H1 satisfies an inequality H1≦1/3*λ/n and the average height H2 satisfies an inequality H2≦1/3*λ/n. An average pitch P between the first structure and the second structure satisfies following conditions: H1/2≦P≦1/3*λ/n, and H2/2≦P≦1/3*λ/n, in which the use wavelength is defined as X and the refractive index relative to the use wavelength is n.

摘要： An object of the present invention is to provide a method for producing a dust core wherein generation of iron oxide at grain boundaries in the dust core is unlikely to take place upon annealing of the dust core subjected to compaction, thus allowing excellent electromagnetic characteristics to be realized. Also, the following is provided: a method for producing a dust core, which comprises: a step of molding a magnetic powder comprising a powder for a dust core formed with an iron-based magnetic powder coated with a silicone resin into a dust core via compaction; and a step of annealing the dust core via heating so as to cause the silicone resin contained in the dust core to be partially formed into a silicate compound, wherein annealing of the dust core is carried out at a dew point of an inert gas of −40° C. or lower in an inert gas atmosphere in the annealing step.
