Title: Strobe light emitting apparatus and camera

Abstract: A strobe apparatus includes a xenon tube, which is a discharge tube, having a discharge light emitting portion and a light emitting portion terminal. Light is emitted from the xenon tube and is reflected in a predetermined direction by a reflection umbrella. A transparent electrode is coated on the external surface of the xenon tube from the discharge light emitting portion to the terminal. When trigger voltage is applied to the xenon tube through the transparent electrode, strobe light is emitted by the discharge light emitting portion. By using the strobe apparatus, the orientation characteristic of the discharge tube can be improved without uneven light distribution and a shortage of a light amount.
