The invention provides an electric vacuum cleaner simplifying structure and preventing light leakage of an illuminant. An air-path forming body (13) is provided with: a flexible pipe body (21) with one end side communicated with a suction inlet side of an electric blower, and the other side provided with a hand-side operation part (27) provided with a holding part (41); a prolonging pipe (22) with one end side connected with the hand-side operation part (27) of the flexible pipe body (21). The air-path forming body (13) is provided with an illuminant at the hand-side operation part (27), for example, the illuminant illuminates light when a dust amount detecting detects a state of the electric vacuum cleaner that dust amount passing by an air path (W) is more than a specified amount, etc. The air-path forming body (13) is provided with a light guide body (57) along the length direction of the prolonging pipe (22), under the state of connection of one end side of the prolonging pipe (22) and the hand-side operation part (27), one end side of the light guide body is opposite to an illuminant (49), and luminescence from the illuminant (49) is guided to the other end side of the light guide body.
