An objective of the present disclosure is to provide an optical coupler and an optical switch capable of achieving stable optical characteristics with low power consumption and more economical efficiency with respect to external factors. In order to achieve the aforementioned object, an optical coupler according to the present disclosure is an optical coupler which couples an optical fiber of a single core disposed in two ferrules using a sleeve, in which a first ferrule of the two ferrules has a plurality of optical fibers disposed in a bundle shape in a fiber hole on the same circumference around a ferrule center axis, at least one of the two ferrules is rotatable about the ferrule center axis, and butted end parts of the two ferrules have a convex spherical shape having a center point on the ferrule center axis.
