An electric cutting device includes: a pair of cutting blades cutting an object by rotating about a rotation central axis; an electric motor for operating the cutting blades; and a guide plate having a recess in a manner of receding along a predetermined direction for housing the object in advance when cutting the object. An edge of the recess includes a pair of linear portions. When a position of the guide plate at a most front end along the predetermined direction is set as a first position, and a position in an operation range of each cutting blade at a most front end along the predetermined direction is set as a second position, a distance between the first position and the second position along the predetermined direction is one-fourth or less of the predetermined interval.
