Abstract
A printed board includes: a base member; a recess portion provided in the base member; a heat dissipation member fitted into the recess portion; and a wiring pattern provided on an upper side of the base member and the heat dissipation member via an insulator. A contact portion in which an inner circumferential surface of the recess portion and an outer circumferential surface of the heat dissipation member contact each other and a separation portion in which those do contact each other are formed. A gap between the recess portion and the heat dissipation member is filled with thermosetting resin of the base member melted by heating. At least a partial portion in a width direction of the wiring pattern passes through a position vertically overlapping the separation portion while an entire portion thereof does not pass through a position vertically overlapping the contact portion.
