Abstract
Provided is a cooler having high cooling efficiency and low pressure loss of fluid. A cooler includes: a flow-channel part at least including a plate-like fin (top plate) and a plate-like fin (bottom plate); and a continuous groove-like flow channel defined between the top plate and the bottom plate to flow fluid, the cooler being configured to cool semiconductor elements. When the flow-channel part is viewed from the direction parallel to the top plate and intersecting the flow channel, the flow channel has a corrugated shape so that a face of the flow channel closer to the top plate and a face of the flow channel closer to the bottom plate bend in a synchronized manner toward the top plate and the bottom plate.
