Summary:An electronic device including: a semiconductor chip on which an integrated circuit is formed; an electrode formed on the semiconductor chip and electrically connected to the integrated circuit; a resin protrusion disposed on the semiconductor chip; an interconnect formed on the electrode and extending over the resin protrusion; a wiring board on which a wiring pattern is formed, the semiconductor chip being mounted on the wiring board so that part of the interconnect positioned over the resin protrusion faces and is electrically connected to the wiring pattern; and an adhesive that bonds the semiconductor chip and the wiring board. The resin protrusion is compressed in a direction in which the distance between the semiconductor chip and the wiring board decreases and is formed of a material having a negative coefficient of thermal expansion.
