    摘要： A projection 23 is formed on a connecting terminal part 22 opposing to a side surface 16 of a ceramic electronic component main body 12 in a terminal member 19 by processing the metal plate which provides this terminal member 19. This projection 23 is made to project toward the side surface 16 of the ceramic electronic component main body 12. The interval more than the predetermined dimension is reliably formed between the connecting terminal part 22 and the side surface 16 of the ceramic electronic component main body 12 by the projection 23. This prevents the solder from reaching even to the ceramic electronic component main body 12.

    摘要： A band-pass filter includes a photonic crystal having a local mode that generates a pass band in a stop band formed by Bragg reflection, a transmission channel that limits electromagnetic waves propagating in the photonic crystal to a mode in which an amplitude direction of an electrical field is a particular direction; and a magnetic field-applying unit for applying to the photonic crystal a DC magnetic field in a direction perpendicular to a propagation direction of the electromagnetic waves. The photonic crystal includes a periodic structure including a low permittivity dielectric member and a plurality of high permittivity dielectric members periodically arranged in the low permittivity dielectric member so that the Bragg reflection occurs in the periodic structure, and a magnetic member disposed in the periodic structure.

    摘要： Photonic crystal units (10a, 10b, and 10c) are formed by an optical molding process using a photocurable resin, and partitions (11) are provided at the boundaries therebetween. The voids in each photonic crystal unit are filled with a second substance containing ceramic particles dispersed therein to form a filled portion 2. A plurality of three-dimensional periodic structure units containing the first and second substances distributed with three-dimensional periodicity are arranged so as to have different ratios between the dielectric constants of the first and second substances. Therefore, present invention provides a three-dimensional periodic structure having a wide photonic band gap which could not be obtained in a conventional three-dimensional periodic structure.
