Abstract
To provide a method for manufacturing a porous glass deposition body for optical fiber without causing deposition unevenness or decreasing the yield, provided is a method of manufacturing a porous glass deposition body by blowing glass fine particles generated from a plurality of burners for glass fine particle synthesis onto a starting member that is moved vertically and rotated on a rotational axis that is a central axis of the starting member. The burners are arranged such that the central axis of each burner shares a plane with the rotational axis of the starting member, and at least two of the planes in which the central axis of one of the burners and the rotational axis of the starting member are arranged form a prescribed angle.
