Abstract:
1. A detection device comprising: a detector unit which is provided on an insulating board at a first side of the board; a circuit component which is provided on the board at a second side of the board and which processes a signal detected by the detector unit; and a wiring unit which penetrates through the board in the thickness direction of the board and connects the detector unit and the circuit component, wherein the wiring unit includes a through-hole electrode which penetrates through the board in the thickness direction of the board, wherein the circuit component is a bare integrated circuit chip which includes a semiconductor substrate and a circuit unit formed on the semiconductor substrate, and the bare chip is mounted on the board at the second side, wherein the bare chip is connected to the board at the second side such that the circuit unit faces the surface of the board at the second side by bump bonding, wherein the semiconductor substrate is electrically connected to a ground pattern formed on the board, wherein the detector unit includes a detection electrode and a counter electrode, the detection electrode being provided on the board at the first side and the counter electrode being disposed such that the counter electrode faces the detection electrode and being movable with respect to the detection electrode, and is constructed as a capacitive sensor which detects a capacitance between the detection electrode and the counter electrode.
