Abstract
A solid electrolytic capacitor includes a flat-shaped anode terminal having a first surface connected to an anode portion of a capacitor element and having a second surface opposite to the first surface, a flat-shaped cathode terminal having a first surface connected to a cathode layer of the capacitor element and having a second surface opposite to the first surface thereof, and an insulating resin package accommodating the capacitor element, the anode terminal, and the cathode terminal. The second surface of the cathode terminal is flush with the second surface of the anode terminal. The second surface of the anode terminal and the second surface of the cathode terminal expose to an outside of the resin package. The anode terminal includes a first thick portion and a first thin portion thinner than the first thick portion. The first thick portion has the second surface of the anode terminal and a portion of the first surface of the anode terminal. The first thin portion has a portion of the first surface of the anode terminal and being connected to the first thick portion. The cathode terminal includes a second thick portion and a second thin portion thinner than the second thick portion. The second thick portion has the second surface of the cathode terminal and a portion of the first surface of the cathode terminal. The second thin portion has a portion of the first surface and being connected to the second thick portion. This solid electrolytic capacitor has a small equivalent series inductance, and is stably mountable to a mount body.
