摘要： An object of the present invention is to allow an optical element to be obtained with good precision using a polymer film and a glass substrate as a reinforcer. The present invention is characterized by the fact that a polymer film is formed on a glass substrate which has been treated to prevent the glass substrate and polymer from separation. This allows an optical circuit pattern to be formed without producing separation between the glass substrate and polymer film when the film is formed. The dimensional precision of the configuration of the distributed index in the polymer film can be maintained generally to the same extent as the expansion and shrinkage of the glass substrate. In addition, a vessel obtained with a glass substrate as the bottom surface can be used as the casting vessel.

摘要： The inductance component has a base material, a coil formed in the base material and an electrode electrically connected to the coil. In addition, an impact-absorption layer is disposed between the electrode and the base material. Forming impact-absorption layer between the base material and the electrode allows the base material to have flexibility even if an impact is given on the base material, providing the component with high impact-resistance.

摘要： A three-dimensional coil pattern, whose internal electrode is connected to external electrodes through a via, is formed within photosensitive resin colored by colorant. This structure allows this electronic component to be lower profile. Cured and colored resin that works as a protecting section of the coil pattern prevents irregular reflection on the internal electrode or the via due to illuminating the component when the component is mounted, so that the component can be handled with more ease.

摘要： A coil electric conductor has an insulating substrate, a first conductive layer, and a second conductive layer. The first conductive layer is formed at a depression provided on a face of the insulating substrate. The second conductive layer is formed on the first conductive layer with the first conductive layer interposed between the second conductive layer and the insulating substrate. This construction realizes a coil electric conductor having a highly precisely uniformized cross-sectional shape.

摘要： The present invention provides a curved optical waveguide with reduced loss. Particularly, it relates to a waveguide with rectangular cross-section which has a curved portion, wherein the relation between the width D of the waveguide at the curved portion and the radius R of the curvature is R/D.ltoreq.500. This waveguide is provided with at least one cladding inside the core of said curved portion, thereby dividing the waveguide at the curved portion in a plurality of narrow optical waveguides. This enables a large reduction of the loss even in curved optical waveguides with sharp curves, and realizes inexpensive optical waveguides.
