The invention relates to a bobbin with multiple steam holes. The bobbin includes a tubular main body, the steam holes are formed in the circumferential surface of the tubular main body and are conicalholes with inner ends larger than the outer ends, and every two adjacent outlet segments of the steam holes are connected with each other through an arc-shaped concave surface. According to the provided bobbin with the steam holes, during yarn steaming, steam easily enters inner-layer yarn, and the bobbin is used for solving the problem that during yarn steaming through existing bobbins, steam isunlikely to be in contact with the inner-layer yarn.
