Abstract: A magnetic sensor includes a ceramic substrate, a GMR layer, and an undercoat layer. The ceramic substrate includes a substrate body and a glazing layer. The substrate body contains a ceramic as a material thereof. The glazing layer is formed on a surface of the substrate body. The GMR layer has a multilayer structure of a plurality of magnetic layers and a plurality of non-magnetic layers. The undercoat layer is formed between the glazing layer and the GMR layer. The undercoat layer contains a BCC solid solution.

Abstract: An image-capturing apparatus comprises a board configured to hold an image sensor, a holding member configured to hold an optical member so as to be insertable into and removable from an optical path, the holding member being held between a lens barrel and the image sensor, and a sealing member configured to surround a periphery of a light receiving surface of the image sensor, the sealing member being provided on a side of the image sensor with respect to the optical member, wherein the sealing member includes a first sealing portion which contact the board and a second sealing portion which contacts the holding member.

Abstract: A fixing component fixes an imaging lens and have a side surface including an opening. A holding frame holds an optical element. A holding base is inserted into the opening from a direction orthogonal to an optical axis of the imaging lens and holds the holding frame. A driving gear drives the holding frame in the direction orthogonal to the optical axis of the imaging lens. The holding base has an engagement portion that engages with the driving gear when the holding base is inserted into the opening.

Abstract: An image-capturing apparatus comprises a fixed portion configured to fix an image-capturing lens, the fixed portion having an opening portion on its side surface, and a holding base configured to be inserted through the opening portion in a direction orthogonal to an optical axis of the image-capturing lens, wherein the holding base holds, slidably with respect to an orthogonal plane which is orthogonal to the optical axis, an optical element holding frame which holds an optical element, the fixed portion includes a first sliding portion in an inside of the fixed portion formed through the opening portion, and the optical element holding frame includes a second sliding portion which slidably contacts the first sliding portion.

Abstract: An optical apparatus includes a holding frame configured to hold an optical element and including a rack, and a driver configured to drive the holding frame. The driver includes a worm rotated by the actuator, a worm wheel configured to form a worm gear together with the worm, and a pinion configured to rotate with a rotation of the worm wheel and engaged with the rack.

Abstract: An image-capturing apparatus comprises an image sensor, a driver configured to incline at least one of the image sensor and an image-capturing optical system with respect to a plane perpendicular to an optical axis of the image-capturing optical system, and a corrector configured to perform shading correction on an image-capturing signal based on an inclination angle of the at least one of the image sensor and the image-capturing optical system with respect to the plane.
