A circuit board including a first insulating layer; a first circuit pattern disposed on the first insulating layer; and a second insulating layer disposed on the first insulating layer and including a cavity. An upper surface of the first insulating layer includes a first region that does not vertically overlap the cavity; a second region vertically overlapping the cavity; and a boundary region between the first region and the second region. The first circuit pattern includes a first-first circuit pattern disposed on the boundary region of the first insulating layer. The first-first circuit pattern includes a first portion that does not vertically overlap the cavity, and a second portion connected to the first portion and vertically overlapping the cavity. A thickness of the first portion of the first-first circuit pattern is different from a thickness of the second portion of the first-first circuit pattern.
