An oil cooler for motor oil used in engines has an element core, a base on which the core is placed, and a casing housing the element core. The core consists of a plurality of sets of two elements being combined together face-to-face and a fin member which is placed on the set of elements. These two elements and one fin member are join together to make a single unit. Several units are contained in the casing of the oil cooler. Cooling water circulates through the flat hollow doughnut-like elements combined. A partition is formed in the interior of the elements combined and a set of cooling water supply hole and exit hole is provided at both the sides of the partition. The core of elements and a base on which the core is placed are brazing adhered or fixed to each other in a hot vacuum furnace and then a dish-like cap is applied to the base. Motor oil to be cooled is led from the engine block to a filter mechanism through several fin members situated between elements. Cooling water is supplied and withdrawn through a pair of pipes connected to the base.
