Provided is a method for producing a non-aqueous electrolyte secondary battery. A negative electrode core of a negative electrode plate has front and back surfaces each with a surface roughness different from the other Rz. In a wound electrode body, a wound negative electrode core-exposed portion is formed at one end portion in the winding axis direction. In the wound negative electrode core-exposed portion, the surface roughness of the negative electrode core-exposed portion on the outer surface side is lower than the surface roughness on the inner surface side. A negative electrode current collector is placed on the outer surface of the wound negative electrode core-exposed portion and the negative electrode current collector is resistance-welded to the wound negative electrode core-exposed portion.

Method for producing secondary battery having negative electrode with different surface roughnesses

A light source includes a semiconductor light emitting device; and a wavelength converter. The wavelength converter includes: a substrate; a phosphor layer disposed on the substrate; and a light reflective layer disposed on the substrate so as to surround the phosphor layer. The phosphor layer includes phosphor particles and a first matrix material in which the phosphor particles are dispersed. The light reflective layer includes inorganic compound particles and a second matrix material in which the inorganic compound particles are dispersed. The inorganic compound particles have a refractive index higher than that of the first matrix material. The first matrix material has a refractive index higher than that of the phosphor particles. The phosphor particles have a refractive index higher than that of the second matrix material.

Light source including wavelength converter

A wavelength conversion member, comprises: a substrate; a first wavelength conversion layer on the substrate, the first wavelength conversion layer containing a first phosphor and a first matrix; and a second wavelength conversion layer containing a second phosphor, first inorganic particles, and a second matrix. The first phosphor and the second phosphor convert at least part of the excitation light incident on the second main surface into first light having longer wavelengths than the excitation light. The first light is emitted from the second main surface of the second wavelength conversion layer. A volume Vp1 of the first phosphor, a volume Vw1 of the first wavelength conversion layer, a volume Vp2 of the second phosphor, and a volume Vw2 of the second wavelength conversion layer satisfy Vp1/Vw1&#x3e;Vp2/Vw2.

Wavelength conversion member including phosphor that converts light from semiconductor light-emitting element into longer-wavelength light

A wavelength converter comprises: phosphor particles; and a matrix that is located between the phosphor particles and comprises zinc oxide crystallites. Pores are included in at least one of the zinc oxide crystallites.

Wavelength converter containing phosphor particles

A method for manufacturing an electronic component package. The method includes (i) providing a package precursor in which an electronic component is embedded such that an electrode of the electronic component is exposed at a surface of a sealing resin layer; (ii) forming a first metal plating layer such that the first metal plating layer is in contact with the exposed surface of the electrode of the electronic component; (iii) disposing a metal foil in face-to-face spaced relationship with respect to the first metal plating layer; and (iv) forming a second metal plating layer. In step (iv), the second metal plating layer is formed so as to fill a clearance between the first metal plating layer and the metal foil, thereby integrating the metal foil, the first metal plating layer and the second metal plating layer with each other.
