Proposed is a holder frame having a holder for fixing an article in a vehicle. The holder frame includes a fixing clip configured to be fitted between a windshield and a dashboard of a vehicle and configured to be fixed by opening elasticity between the windshield and the dashboard of the vehicle, and a dashboard frame composed of a first section coupled to a bottom of the fixing clip, a body extending from the first section across a dashboard of a vehicle, and a second section to which a holding unit for holding an object can be coupled. The fixing clip is provided in an open structure of which both ends opening at an acute angle are spaced apart from each other, thereby being able to additionally fix an article that is held inside a windshield.

A method for manufacturing a printed circuit board with a capacitor embedded therein which has a dielectric film using laser lift off, and a capacitor manufactured thereby. In the method, a dielectric film is formed on a transparent substrate and heat-treated. A first conductive layer is formed on the heat-treated dielectric film. A laser beam is irradiated onto a stack formed, from below the transparent substrate, to separate the transparent substrate from the stack. After the transparent substrate is separated from the stack, a second conductive layer is formed with a predetermined pattern on the dielectric film. Also, an insulating layer and a third conductive layer are formed on the first and second conductive layers to alternate with each other in a predetermined number.

An electric double layer capacitor and a method for manufacturing the same, in which one or more projections are formed on an inner bottom surface of a lower case, which is a concave container made of ceramic, in a the process of sequentially stacking a lower electrode, a separator, and an upper electrode in the lower case and covering the lower case with a sealing plate. It is possible to eliminate the process of injecting a bonding liquid and strongly connect the lower electrode and the upper electrode to the lower case and the sealing plate, respectively, by means of the projections, thus preventing the occurrence of a short circuit and reducing the equivalent series resistance.
