Abstract: A blood pressure measurement device includes an outer case; a base; a pump provided on a surface of the base such that the pump is shifted from a center of the outer case and located on one side as viewed in a circumferential direction of a living body; a first pressure sensor and a second pressure sensor that are provided such that the first pressure sensor and the second pressure sensor are arranged side by side in the circumferential direction and located on one side as viewed in a direction orthogonal to the circumferential direction; and a first on-off valve and a second on-off valve that are provided such that the first on-off valve and the second on-off valve are arranged side by side in the circumferential direction with reference to the first pressure sensor and the second pressure sensor.

Abstract: According to one embodiment, an electronic apparatus includes a housing, a circuit board, a component, and a reinforcing portion. The circuit board is in the housing and includes a first surface and a second surface opposite to the first surface. The component is on the first surface of the circuit board and includes a corner. The reinforcing portion is on the second surface of the circuit board and corresponds to the corner of the component.

Abstract: According to one embodiment, an electronic apparatus includes a housing, a circuit board in the housing, a heat sink, and a fixing portion. The circuit board includes a heating component. The heat sink has a plate shape and faces the heating component. The fixing portion is attached to the heat sink and fixed to the circuit board at least at two points.

Abstract: According to one embodiment, a printed wiring board, on which a circuit component including a pad is to be mounted, is provided with a pad which is to be electrically connected to the pad of the circuit component through a conductive joint member. The pad of the printed wiring board includes a separated portion which is located in a peripheral portion thereof and electrically independent of other portion of the pad of the printed wiring board.

Abstract: A card-type electronic device has a multilayer printed wiring board and a case which houses the multilayer printed wiring board. The case has an opening. The multilayer printed wiring board includes a plurality of insulating layers and a plurality of conductive layers, which are alternately stacked, and has a flat surface on one side thereof along a stacked direction. The flat surface is formed of one of the insulating layers, and at least a part of the flat surface is exposed to the outside of the case through the opening.
