An image pickup apparatus includes an image sensor, a lens, and an electric module disposed outside the lens when viewed in a first direction. The electric module includes a first inductor, a first transformer, a second inductor, and a second transformer. A second terminal of the first inductor is connected to a third terminal of the first primary winding. A fifth terminal of the second inductor is connected to a seventh terminal of the second primary winding. The first inductor is wound clockwise from a first terminal toward the second terminal. The second inductor is wound counterclockwise from a sixth terminal toward the fifth terminal. The first primary winding is wound counterclockwise from the third terminal toward a fourth terminal. The second primary winding is wound clockwise from the seventh terminal toward the eighth terminal.

Image pickup apparatus and lens barrel

An imaging apparatus includes: an imaging device in which photoelectric conversion elements are arranged in an array; a wiring component in which the imaging device is mounted and a power source wiring is provided; connection wirings that connects the power source wiring and the imaging device each other; at least two power supply sources connected to the power source wiring; and at least one power supply source connected to the power source wiring, the power supply sources supply power to the imaging device via the power source wiring and the connection wirings, at a horizontal synchronization frequency of the imaging device, the two power supply sources have lower impedances than the one power supply source, and at least one of the connection wirings is connected to a wiring path connecting the two power supply sources in the power source wiring.

Imaging apparatus and electronic equipment

An image capturing apparatus includes a printed wiring board and an inductor. The inductor includes a winding wire portion, a pair of wire portions drawn out from the winding wire portion to a first side in a first direction, and a pair of electrodes connected to the pair of wire portions. The printed wiring board includes a pair of pads connected to the pair of electrodes, and a pair of wiring patterns extending from the pair of pads. Each of the pair of wiring patterns extends from a first portion of corresponding one of the pair of pads. The first portion is a portion extending from an end of the corresponding one of the pair of pads on a second side in the first direction to a length that is two thirds of a length of the corresponding one of the pair of pads in the first direction.

Image capturing apparatus, lens barrel, and printed circuit board

An image pickup unit includes an image pickup element and a wiring board. The image pickup element includes an analog circuit. The analog circuit includes an analog ground wiring. The image pickup element is mounted on the wiring board. The wiring board includes a first ground wiring that is connected to the analog ground wiring and forms a closed loop with the analog ground wiring in a side view of the image pickup unit, and a second ground wiring that is connected to the first ground wiring via only a first via conductor.
