Claim:
1. An electronic device comprising: a substrate having a main surface and a back surface that are mutually opposite in a thickness direction of the substrate, the substrate being made of a semiconductor material; a main electronic element; an auxiliary electronic element; a conducting layer electrically connected to the main electronic element; and an insulating layer, wherein the substrate is formed with an element arrangement recessed portion that is recessed from the main surface, the main electronic element being arranged in the element arrangement recessed portion, the element arrangement recessed portion has an element arrangement recessed portion bottom surface facing in the thickness direction and an element arrangement recessed portion side surface inclined with respect to the thickness direction, the auxiliary electronic element is provided on the element arrangement recessed portion side surface, the insulating layer includes a recessed portion inner surface insulating portion covering at least the element arrangement recessed portion side surface, the auxiliary electronic element is a resistor, the recessed portion inner surface insulating portion includes a first insulating layer disposed on the element arrangement recessed portion side surface, and a second insulating layer located away from the element arrangement recessed portion side surface, the resistor being provided between the first insulating layer and the second insulating layer, and the second insulating layer has an insulating layer through-hole through which the resistor and the conducting layer are connected.
