Abstract: An electrolytic capacitor includes an anode body having a porous structure, an anode lead having a sheet shape, a dielectric layer disposed on a surface of the anode body, a cathode layer covering at least a part of the dielectric layer, an anode lead frame electrically connected to the anode lead, and a cathode lead frame electrically connected to the cathode lead. The anode lead includes an embedded portion embedded in the anode body and a protrusion portion protruding to an outside of the anode body. The anode lead has a first main surface facing the cathode lead frame and a second main surface opposite to the first main surface. The anode lead is located between a center of the anode body and an end face of the anode body in a first direction in which the first main surface faces the cathode lead frame. The end face of the anode body is positioned at a side close to the cathode lead frame.

Abstract: A light source device includes an excitation light source, and a fluorescence layer configured to emit fluorescence by receiving excitation light emitted from the excitation tight source. The fluorescence layer includes at least one selected from a group consisting of a first fluorescent substance and a second fluorescent substance. The first fluorescent substance is configured to emit fluorescence having a peak wavelength ranging :from 400 nm to 510 nm, inclusive, by receiving the excitation light. The second fluorescent substance is configured to emit fluorescence having a peak wavelength ranging from 580 nm to 700 nm, inclusive, by receiving the excitation light. The first fluorescent substance and the second fluorescent substance each have a fluorescence lifetime ranging from 0.1 nanoseconds to 250 nanoseconds, inclusive. Energy density of the excitation light is 10 W/mm2 or more.

Abstract: An electrolytic capacitor includes an anode body having a porous structure, an anode lead partially embedded in the anode body, a dielectric layer formed on a surface of the anode body, and a cathode part that covers at least part of the dielectric layer. The anode body has a first region in which first particles sintered together and a second region in which second particles sintered together. The average particle diameter D1 of the first particles is smaller than the average particle diameter D2 of the second particles. The volume-based pore diameter distribution of the anode body with the dielectric layer has a first peak in a range of less than or equal to 0.5 μm in pore diameter, and a second peak in a range of more than 0.5 μm in pore diameter.
