A PORTABLE ELECTRONIC DEVICE COMPRISING A FOLDED The application relates to a portable electronic device comprising a) a folded substrate carrying components of the device, and b) another, separate component having a fixed outer contour, and c) a housing for enclosing said folded substrate and said separate component, said housing having an inner contour, wherein said folded substrate is folded from a planar substrate along a folding line, said folded substrate exhibiting outer edges comprising a folded edge following said folding line. The application further relates to a method of manufacturing a folded substrate. The object of the present application is to facilitate miniaturization of a portable electronic device, such as a hearing aid. The problem is solved in that the folded substrate is shaped to provide that at least one of said outer edges follow(s) the fixed outer contour of the separate component and/or the inner contour of said housing. This has the advantage of providing a larger area on the substrate to place components and soldering points thereby improving the use of the available space in the portable electronic device. The invention may e.g. be used in electronic devices where volume utilization is an important design parameter, e.g. hearing aids comprising a part adapted for being mounted in an ear canal of a user, e.g. in the bony part of the ear canal.
