Mixer unit and hand-held blender

The invention discloses a mixer unit and a hand-held blender. The present invention provides a mixer unit capable of further improving cutting performance for cutting a to-be-processed object. The mixer unit includes a bell-shaped cover with an opening therebelow, a rotation shaft (8) which is set to extend in the up-down direction inside the cover, and a blade unit (9) provided on the rotation shaft (8). The blade unit (9) includes a main blade (21) extending in the lateral direction from the rotary shaft (8), and a sub-blade (22) of which a tip portion (22a) is located above the main blade (21). The sub-blade can rotate around the rotary shaft (8) at a position closer to the rotary shaft (8) than the main insert (21). The sub-blade (22) has a cutting edge (22b) capable of cutting the to-be-processed object at the front end portion in the rotation direction. 本发明提供种能够进步提高对被调理物进行切削的切削性能的混合器单元。混合器单元包括：吊钟形状的罩，其下方开口；旋转轴(8)，其被设为在罩的内侧沿上下方向延伸；以及刀片单元(9)，其设于旋转轴(8)。刀片单元(9)包括：主刀片(21)，其自旋转轴(8)沿横向延伸；以及副刀片(22)，其顶端部(22a)位于比
