In an optical system according to each exemplary embodiment, an interval between adjacent lens units changes in focusing from an infinite-distance object to a close-distance object, and a first in-focus state in which β=−1.2 is obtained can be caused, where β is a lateral magnification of an entire system. The optical system according to each exemplary embodiment includes a plurality of focus lens units, and out of a focus lens unit having a largest absolute value of a focus sensitivity and a focus lens unit having a second largest absolute value of a focus sensitivity in a state in which focus is put on an infinite-distance object, a focus lens unit disposed on an object side is a lens unit LA, and a focus lens unit disposed on an image side is a lens unit LB. A partial optical system LC including all lenses disposed on the image side of the lens unit LB has negative refractive power. The partial optical system LC satisfies a predetermined conditional expression.

There is provided a method for laminating a smooth thin resin layer on a substrate in manufacturing a liquid ejection head by a casting method. To achieve this, a resin layer having a sufficient thickness to fill a concave portion already existing on the substrate is applied and smoothed. Thereafter, a plurality of opening patterns (concave portions) are formed and then smoothed again to obtain a thin resin layer having a desired thickness.
