SOLUTION: This invention relates to the range hood disposed at an upper part of a heating cooker. This range hood 1 has a suction opening 10 opposed to the heating cooker and sucking the air, and discharge openings 14b, 14c, 14d extending around at least a part of the suction opening 10 in the circumferential direction and discharging the air forming the air curtain toward a heating cooker side. The discharge openings 14b, 14c, 14d have width change parts 28 having width change outline of which a width is changed in the circumferential direction. The width change part 28 has at least two constant-width areas 46 extending with a constant width in the circumferential direction, and a wide-width area 48 formed between the constant-width areas 46, having a width wider than the width of the constant-width areas 46, and formed at a suction opening side.
