Abstract
In an image pickup unit, an image pickup device, a first substrate, and a second substrate are connected in the order from a distal end. The image pickup unit includes a cutout that is provided in a side surface of the first substrate, penetrates from a distal end surface to a proximal end surface, and has a smaller width dimension of an opening on the proximal end surface side than that of an opening of the distal end surface side, and a resin filled in the cutout, a gap between the image pickup device and the first substrate, and a gap between the first substrate and the second substrate.
Claims12
An image pickup unit comprising:
- an image pickup device, a first substrate, and a second substrate, the image pickup device, the first substrate, and the second substrate being connected in order from a distal end of the image pickup unit,
- the image pickup unit further comprising:
- a cutout that is provided on a side surface of the first substrate and penetrates from a distal end surface to a proximal end surface, the cutout being formed such that a width dimension of a second opening on a side of the proximal end surface is smaller than a width dimension of a first opening on a side of the distal end surface in a direction along the side surface;
- and
- a resin filled in the cutout, a gap between the image pickup device and the first substrate, and a gap between the first substrate and the second substrate.
An endoscope comprising:
- an insertion portion configured to be inserted in a subject;
- and
- an image pickup unit that is provided in the insertion portion, and includes an image pickup device, a first substrate, and a second substrate, the image pickup device, the first substrate, and the second substrate being connected in order from a distal end of the image pickup unit, wherein
- the image pickup unit further comprising:
- a cutout that is provided on a side surface of the first substrate and penetrates from a distal end surface to a proximal end surface, the cutout being formed such that a width dimension of a second opening on a side of the proximal end surface is smaller than a width dimension of a first opening on a side of the distal end surface in a direction along the side surface;
- and
- a resin filled in the cutout, a gap between the image pickup device and the first substrate, and a gap between the first substrate and the second substrate.
An image pickup unit comprising:
- an image pickup device, a first substrate, and a second substrate, the image pickup device, the first substrate, and the second substrate being connected in order from a distal end of the image pickup unit,
- the image pickup unit further comprising:
- a cutout that is provided on a side surface of the first substrate and penetrates from a distal end surface to a proximal end surface, the cutout being formed such that a width dimension of a second opening on a side of the proximal end surface is larger than a width dimension of a first opening on a side of the distal end surface in a direction along the side surface;
- and
- a resin filled in the cutout, a gap between the image pickup device and the first substrate, and a gap between the first substrate and the second substrate.
