Abstract

Provided is a cooler that is less likely to cause an uneven degree of cooling during cooling of multiple cooling targets. The cooler is thus provided inside with a flow path of a refrigerant, the flow path including: an outer-peripheral-side header region that is provided on an outer peripheral side of an annular shape and extends in a circumferential direction of the annular shape; an inner-peripheral-side header region that is provided on an inner peripheral side of the annular shape across a separation region from the outer-peripheral-side header region and extends in the circumferential direction; and a fin region serving as the separation region in which a fin is disposed.
