Abstract: A conductive paste for an electrolytic capacitor used for connecting a cathode part and a cathode lead terminal of the electrolytic capacitor. The conductive paste includes a thermosetting resin, and conductive particles, and the conductive particles include flaky metal particles and acicular conductive particles. The content of the conductive particles in the conductive paste is, for example, 50 mass % or more and 70 mass % or less, and the mass ratio of the flaky metal particles to the total of the flaky metal particles and the acicular conductive particles is, for example, 60% or more and 80% or less.

Abstract: A wavelength conversion device includes a substrate, a matrix supported by the substrate and containing inorganic material, a phosphor embedded in the matrix, and filler particles embedded in the matrix. A linear expansion coefficient of the filler particles is equal to or larger than 25 ppm/K and equal to or smaller than 790 ppm/K, and is larger than a linear expansion coefficient of the matrix. This wavelength conversion device suppresses warping of the substrate.

Abstract: A wavelength conversion device of the present disclosure includes a substrate, a phosphor layer that has a matrix containing zinc oxide and phosphor particles embedded in the matrix and that is supported by the substrate, a dielectric layer disposed between the substrate and the phosphor layer, and a protective layer that is disposed between the phosphor layer and the dielectric layer and that has an isoelectric point equal to or larger than 7. A main surface of the substrate includes, for example, first and second regions. The phosphor layer covers, for example, only the first region out of the first and second regions.

Abstract: A projection apparatus of the present disclosure includes a light-emitting element for emitting excitation light, a wavelength converter for receiving the excitation light, converting the excitation light into light of a different wavelength, and emitting the converted light as radiation light, and an optical filter for receiving the radiation light. The optical filter reflects long-wavelength light of wavelengths longer than wavelengths of the radiation light. With this configuration, the optical filter reflects long-wavelength light of wavelengths longer than wavelengths of the radiation light, thus being able to prevent the wavelength converter from being irradiated with long-wavelength light, and being able to prevent deterioration of the wavelength converter.

Abstract: A lamp includes: first and second semiconductor light-emitting elements adapted to emit excitation light; a wavelength conversion element adapted to convert the excitation light into light having a peak wavelength different from that of the excitation light; and a concave mirror adapted to reflect the excitation light emitted from the semiconductor light-emitting elements to the wavelength conversion element and reflect the light from the wavelength conversion element toward an outside of the lamp. A distance y1 from an optical axis of the first semiconductor light-emitting element to an optical axis of the concave mirror satisfies (D+Dphos)/2≦y1≦4f, and a distance y2 from an optical axis of the second semiconductor light-emitting element to the optical axis of the concave mirror satisfies 4f
