Abstract: A laser processing apparatus includes a light source configured to emit laser light; a power supply configured to supply a current to the light source; a deflection unit on an optical path of the laser light and including an optical element configured to change an amount of transmission of the laser light to deflect at least a part of the laser light; an optical separation unit on the optical path of the laser light and being configured to shield higher-order light included in the laser light and deflected by the optical element in the deflection unit, and transmit zero-order light that is included in the laser light and passes through the deflection unit; and a signal synchronization unit configured to control the power supply to selectively turn the current on or off in synchronization with a timing at which the higher-order light is deflected by the optical element.

Abstract: A battery includes a metal battery can that has a tubular portion having an opening edge portion and a bottom portion; an electrode body that is in the battery can; an electrolytic solution that fills the battery can; and a sealing member that has an outer peripheral surface facing an inner peripheral surface of the opening edge portion of the tubular portion and is configured to seal the opening edge portion. A part of the inner peripheral surface of the opening edge portion and a part of the outer peripheral surface of the sealing member are joined by a melting portion, and a preventing portion is on the outer peripheral surface of the sealing member, the preventing portion being configured to prevent the electrolytic solution from rising toward a position, in which the melting portion is formed.
