PROBLEM TO BE SOLVED: To provide a method which is less damaging to leaves of wakame seaweed when the leaves are cut from a stem.SOLUTION: A stem of wakame seaweed is horizontally or approximately horizontally placed sideways, and liquid is poured over at least both or either side of an upper face and a lower face of the stem so that leaves of the wakame seaweed are pushed aside and an area where leaves come out is exposed. While placing a knife or irradiating laser on the area where leaves come out, the wakame seaweed and knife or the wakame seaweed and laser are relatively moved in a longitudinal direction to cut leaves from that area and separate them from the stem.SELECTED DRAWING: Figure 1【課題】 わかめの葉を茎から切り離す際に、葉を傷めにくくする。【解決手段】 わかめの茎を水平或いはほぼ水平の横向きにし、少なくともその茎の上面と下面の双方又はいずれか一方の面に液体を掛けて、わかめの葉を茎からずらして葉の生え際付近を露出させ、前記生え際付近に刃物又はレーザを当てながら、わかめと刃物又はわかめとレーザを茎の長手方向に相対的に移動させて、葉を生え際付近から切断して茎から分離する。【選択図】図１
