Abstract
A distal end component includes: a transparent resin outer layer portion that is made of a transparent first resin member and configures a surface of a distal end portion; an internal structure portion that is made of a second resin member and is provided in tight contact with an inner surface of the transparent resin outer layer portion; a plurality of component fixing holes provided in the internal structure portion; and lens sections provided in the transparent resin outer layer portion, the lens sections respectively facing distal end surfaces of illumination optical sections and a distal end surface of an observation optical section
Claims4
A resin distal end component for an endoscope, comprising:
- a transparent resin outer layer portion that is made of a transparent first resin member and forms a surface of a distal end portion of an insertion section;
- an internal structure portion that is made of a second resin member different from the first resin member, and is provided in tight contact with an inner surface of the transparent resin outer layer portion;
- a plurality of component fixing holes in which distal-end-side end portions of components provided in the insertion section are respectively disposed, the component fixing holes being provided in the internal structure portion;
- and
- lens sections provided in the transparent resin outer layer portion, the lens sections respectively facing distal end surfaces of optical components disposed in the insertion section, the optical components each having a distal-end-side end portion disposed in a corresponding component fixing hole of the component fixing holes.
