PROBLEM TO BE SOLVED: To provide a static capacitance type sensor with high accuracy in spite of a simple structure, a static capacitance type sensor parts and an article mount body provided with the static capacitance type sensor parts. SOLUTION: An arm 10 is formed, where an insulator 11, a detection electrode 32, and shield electrodes 21, 31, 41 are integrated. The shield electrode 31 is placed around the detection electrode 32, the shield electrode 41 is placed under a detection section detection electrode 322 and an electrode introduction section detection electrode 321 of the detection electrode 32, and the shield electrode 21 shielding the electrode introduction section detection electrode 321 without shielding the detection section detection electrode 322 of the detection electrode 32 is provided. The detection electrode 32 is connected to an inverting input terminal of an operational amplifier via a signal line, a feedback impedance is connected between an output terminal and the inverting input terminal of the operational amplifier, an AC signal generating means is connected to a noninverting input terminal of the operational amplifier, the signal line is shielded and the shield electrodes 21, 31, 41 are connected to the noninverting input terminal of the operational amplifier and a shield means connected to the AC signal generating means.
