The side wall portion includes first to Nth side wall plates 31 to 35 and a side wall hinge portion Hs connecting the first to N side wall plates 31 to 35 so as to open and close them. The first and second end face portions are provided with end side hinge portions He which are connected to any one of the first to Nth side wall plates so as to be openable and closable. If the first to Nth side wall boards are opened, the ingredients for sushi can be filled in, the sushi can be molded by closing the side wall plate and surrounding and pressing the ingredients. By keeping the closed state of the side wall plate by the fixing means 4, it can be used as a storage / portable container of sushi.(FIG.【課題】多角形断面を有した巻き寿司を手軽に成形(調理)できるとともに、成形後にそのまま保管し、弁当箱として携帯可能な寿司成形器を提供する。【解決手段】寿司成形器10は、多角形(N≧3)の平面1a,2aを有した第1・第2端面部1,2と、第1・第2端面部の間に延びた側壁部3と、第1・第2端面部と側壁部とを一時的に連結・保持可能な固定手段4とを備える。側壁部は、第1~第Nの側壁板31~35と、これらを開閉可能に連結する側壁ヒンジ部Hsとを備える。第1・第2端面部は、第1~第Nの側壁板のいずれかに開閉可能に連結する端側ヒンジ部Heを備える。第1~第Nの側壁板を開いた状態にすれば、寿司用の具材を詰め込むことができ、側壁板を閉じて具材を包囲・押圧すれば、寿司を成形することができる。固定手段4で側壁板の閉鎖状態を保持することで、寿司の保管・携帯容器としても使用可能となる。【選択図】図1
