Endoscope and distal end body

An endoscope, comprising:

• a distal end body that is positioned at a distal end of an insertion portion configured to be inserted into a subject;
• and
• a first built-in component and a second built-in component each having a distal end portion housed in the distal end body, wherein
• the distal end body comprises:
• a first housing portion that extends along a first direction along a longitudinal direction of the distal end body and houses the distal end portion of the first built-in component;
• a first opening portion in which the distal end portion of the first built-in component is fitted, the first opening portion communicating with the first housing portion and being open in at least a second direction;
• a second housing portion that communicates with the first housing portion, extends along the first direction at a position shifted in a third direction orthogonal to both the first direction and the second direction, and houses the distal end portion of the second built-in component;
• and
• a second opening portion in which the distal end portion of the second built-in component is fitted, the second opening portion communicating with the second housing portion and being open in at least the second direction,
• wherein the second direction is a direction orthogonal to the first direction,
• the distal end body is configured such that the distal end portion of the first built-in component, from a state where the distal end portion of the first built-in component is fitted into the first opening portion of the distal end body, configured to be slid in a first inserting direction having a component in the second direction to allow attachment and detachment relative to the distal end body and such that the distal end portion of the second built-in component, from a state where the distal end portion of the second built-in component is fitted into the second opening portion of the distal end body, configured to be slid in a second inserting direction having at least a component in the second direction to allow attachment and detachment relative to the distal end body;
• and
• the first inserting direction excludes the first built-in component being slid only in the second direction and the second inserting direction excludes the second built-in component being slid only in the second direction.
