摘要： A heater holder includes a restriction portion and a recessed portion. The restriction portion determines the position of a cable in the longitudinal direction of the heater. The recessed portion, against which a bare conductive portion of the cable is to be positioned, is provided at a position that is different from the position of the restriction portion as viewed in a direction intersecting with the longitudinal direction. A wire is joined to the bare conductive portion somewhere between the restriction portion and the recessed portion.

摘要： An imaging optical system of the present invention includes first and second optical elements arranged in order from an object side and an aperture stop. Each of the first and second optical elements includes an aspherical surface which is rotationally asymmetric with respect to an optical axis. A curvature of the aspherical surface in a first cross section including the optical axis changes from the optical axis in a first direction perpendicular to the first cross section. A total length of the imaging optical system, a distance between the aspherical surface closest to the object side and the aperture stop, and Abbe numbers of the first and second optical elements are appropriately set.
