Abstract: An electrolytic capacitor includes an anode body that includes a porous body and a dielectric layer covering the porous body, and a solid electrolyte layer that covers the dielectric layer. The porous body has a first region located near an outer surface of the porous body, and a second region other than the first region. The first region is a region in which a distance from the outer surface of the porous body is shorter than 0.5D, where D is a shortest distance between the outer surface of the porous body and a center of the porous body. A filling proportion R2 of the solid electrolyte layer in the second region is less than a filling proportion R1 of the solid electrolyte layer in the first region. A ratio R2/R1 of the filling proportion R2 to the filling proportion R1 is less than or equal to 1/10.

Abstract: The present disclosure aims to enhance controllability of a lighting apparatus and increase durability. A lighting apparatus includes a light source; a condenser that converges first light emitted from the light source onto a predetermined focal position of a wavelength conversion element as converged light; the wavelength conversion element that receives the converged light and emits second light at an emission point; and a projection lens that projects the second light as projection light. The lighting apparatus changes the focal position of the condenser lens to change the emission point of the second light to the projection lens, thereby being capable of projecting the second light in any direction.
