Abstract: A method for producing a power storage device includes a process of insert-molding. This process is to relatively move a first mold and a second mold to press a terminal top surface of a terminal member by a top-face close-contact portion of the first mold to a second-mold side and to press a to-be-contacted portion of the terminal member by a contact portion of the second mold to a first-mold side so that a deformed portion of the terminal member is elastically deformed. A resin member is thus insert-molded while the terminal top surface is pressed and tightly contacted with the top-face contact portion.

The porous member has a bore coincident with the center of the reflecting surface of the reflecting mirror, at which the laser beam is reflected, and is open on the side opposite the reflecting mirror. Cooling fluid is permitted to flow into the porous member through the bore thereof to improve the heat exchange between the cooling fluid and reflecting mirror, thus improving the cooling capacity and also permitting effective cooling of the reflecting portion of the reflecting mirror, at which the laser beam is reflected.
