The invention relates to a method for producing an ion transport tube, suitable for transporting ions through an ion transport chamber formed as an inner hollow space of the ion transport tube by means of an electrical field, which can be generated by applying electrical potentials to electrodes of the ion transport tube, comprising the following production steps: a) providing a material block, wherein a plurality of electrically conductive electrode layers are arranged overlapping along a longitudinal axis of the material block, behind one another and substantially in parallel to one another, wherein respective neighbouring electrode layers are at a distance to one another and at least one respective layer made of an insulation material is provided in the intermediate space formed in this way between neighbouring electrode layers, via which the neighbouring electrode layers are adhered to one another and electrically insulated from one another; b) generating a hollow space in the material block, in order to
