Electronic device

An electronic device according to the present disclosure includes a semiconductor substrate, a chip, and a bump. The chip has a thermal expansion coefficient different from that of the semiconductor substrate. The bump connects the connection pads provided on the opposing principal surfaces of the semiconductor substrate and the chip. The bump has a porous metal layer and a metal film. The metal film is provided on at least one of a portion between the connection pad provided on the semiconductor substrate and the porous metal layer and a portion between the connection pad provided on the chip and the porous metal layer, and on the side surfaces of the porous metal layer.
