Abstract: In an electronic apparatus, a case houses an electronic apparatus main body and is electrically conductive. A terminal block is attached to a case wall of the case. In the terminal block, a main body portion is composed of an insulating material. An external terminal is inserted into a through-hole formed in the case wall, and is connected to the electronic apparatus main body. A capacitor is disposed inside the main body portion. An elastic member is disposed inside the main body portion, is composed of a conductive material, is interposed at least one of between the capacitor and the external terminal, and between the capacitor and the case wall, and fixes the capacitor inside the main body portion by pressing the capacitor. The capacitor and the elastic member configure a filter circuit that allows a noise current included in the external terminal to flow to the case wall.

Abstract: A power supply device includes a transformer, a primary semiconductor component, a secondary semiconductor component, a choke coil and a circuit board. Electronic components which include the transformer, the primary semiconductor component, the secondary semiconductor component, and the choke coil, are stacked in pairs, in a normal direction of a board. One pair forms a first stacked body and another pair to forms a second stacked body. A circuit board is interposed between the one pair of electronic components which forms the first stacked body, and also between the other pair of electronic components which forms the second stacked body.
