Abstract: A sound absorbing and insulating member alternately brought into contact with a first partition member and a second partition member. The sound absorbing and insulating member has a plurality of hollow protrusions protruding so as to traverse a gap between the partition members. There is a first and second space between the first and second partition member. The first space is formed in each protrusion and is closed by the first partition member. The second space is provided between adjacent protrusions and is closed by the second partition member.

Abstract: In a first step, a molding die is immersed in a raw liquid including cellulosic fibers. Then, the liquid of a raw liquid is sucked through a net material by a liquid suction part, so as to cause the cellulosic fibers to be laminated on the net material. In the second step, the cellulosic fibers laminated on the net material are dried, so as to form a protrusion. In the third step, the dried protrusion and the communication part are removed from the molding die. A passage part of the communication part is formed at a position where a projection portion had been arranged, the passage part being configured to communicate an inside of the protrusion with an outside of the protrusion.

Abstract: A coating apparatus includes a discharge unit, moving unit, and a controller. The discharge unit includes a nozzle array in which a plurality of nozzles is arranged, and discharges a coating material from each of the plurality of nozzles. The moving unit moves a position of the discharge unit with respect to a to-be-coated surface along a plurality of paths substantially orthogonal to the nozzle array.
