NOVELTY - The device i.e. sensor (80), has a relay substrate (82) i.e. integrated circuit, connected on a base substrate (81). A function element i.e. sensor device (1), is connected through jointing material i.e. resin adhesive (84), formed as bump on the relay substrate, where external shape of the relay substrate is settled inside external shape of the function element in planar view. An element piece (3) is accommodated in an interior space formed between first base material i.e. insulated substrate (2), and a second base material i.e. cover unit (5).    USE - Electronic device e.g. sensor such as physical-quantity sensor e.g. angular velocity sensor, for measuring physical quantities e.g. acceleration and angular velocity, in a mobile type personal computer i.e. notebook type personal computer, a mobile telephone and a digital still camera utilized for an electronic control unit (ECU) for controlling tire in a mobile body (claimed) i.e. motor vehicle. Can also be used in an inkjet type discharge apparatus i.e. ink jet printer, TV, video camera, videotape recorder, car navigation apparatus, pager, electronic organizer, laptop type personal computer, electronic dictionary, calculator, electronic game machine device, word processor, workstation, video telephone, TV monitor for crime prevention, electronic binocular, POS terminal, medical device e.g. electronic thermometer, blood pressure meter, blood-glucose meter, ECG measuring device, ultrasound diagnosing device and electronic endoscope, fish finder, measurement apparatus and measuring instruments in an aircraft, boat and ship and flight simulator, keyless entry system, immobilizer, car navigation system, car air-conditioner, anti-lock brake system (ABS), airbag, tire pressure monitoring system, tire pressure monitoring system (TPMS), engine control unit, battery monitor unit and vehicle body attitude control system in a hybrid vehicle or an electric vehicle.    ADVANTAGE - The function element is connected through the jointing material formed as bump on the relay substrate such that the external shape of the relay substrate is settled inside external shape of the function element in planar view, so that stress of the substrate connected to the function element is reduced to suppress the dispersion of incorrect measurement of an element part, thus improving measurement precision by suppressing characteristic change of the function element by stress, and hence stabilizing characteristics of the mobile body.
