Abstract
A loop heat pipe includes: an evaporator configured to vaporize a working fluid; a condenser configured to liquefy the working fluid; a liquid pipe that connects the evaporator and the condenser to each other; and a vapor pipe that connects the evaporator and the condenser to each other. The condenser includes: a first outer metal layer; a second outer metal layer; and an inner metal layer that is provided between the first outer metal layer and the second outer metal layer, and having a flow channel through which the working fluid flows. The first outer metal layer includes: a first inner face that contacts the inner metal layer; a first outer face opposite to the first inner face in a thickness direction of the first outer metal layer; and a first recess provided in the first outer face so as not to overlap the flow channel in plan view.
