Abstract
A heat radiating substrate () includes an insulating layer () and a circuit pattern () of a metal formed on the insulating layer () in direct contact with the insulating layer (), in which a side surface (that is, metal layer side surface ()) of the circuit pattern () has a region in which an angle θ formed by a surface (insulating layer upper surface (a)) of the insulating layer () (insulating substrate) and a tangential line L at a middle portion (X) in a height direction in a cross-sectional view perpendicular to an extending direction of the metal is 80 degrees or more and 100 degrees or less.
