Abstract: The present invention relates to a method for manufacturing an ink cartridge. The ink cartridge has a container having storage chambers and porous members for holding ink. The porous member is stored in the corresponding storage chambers. The container has ink supply ports for conducting ink from the storage chambers. Before insertion, each porous member is inclined relative to the storage chamber and inserted into the storage chamber through an opening of the container. Therefore, the porous members are easily inserted.

Abstract: A thick-film printed circuit board and a method for producing the same are disclosed, in which wiring conductors having connecting sections for connection with solder electrodes of an electronic element such as a semiconductor chip are provided on an insulating substrate. A layer of insulating material having through holes at positions corresponding to the connecting terminals of the electronic element is covered on the wiring conductors. Conductor pedestals for connection with the electronic element are filled in the through holes and formed on the insulating layer. Each of the pedestals has an area for contact with the connecting terminals of the electronic element.
