Adhere and seal between. Any of the above-mentioned adhesives may be used as long as it has a necessary adhesive force and a good sealing property. The water channel has the same length as the panel material 1 forming the bottom wall a and the panel material 1 forming the side wall b to reduce the number of parts. A difference may be provided between the bottom wall and the side wall depending on the target cross-sectional shape of the water channel.
