A variable capacitance type capacitor comprising: an inside member; and an outside member including a space for housing the inside member; the inside member having a columnar shape, and having a first conductor pattern formed on a circumferential surface of the inside member; the outside member being a dielectric having a predetermined dielectric constant, and having a second conductor pattern formed on an outer circumferential surface of the outside member, the second conductor pattern being disposed so as to oppose the first conductor pattern formed on the circumferential surface of the inside member when the inside member is housed in the space of the outside member; and the inside member housed in the space of the outside member and having the columnar shape being displaced relative to the outside member in a direction of a central axis of the inside member having the columnar shape in response to an externally applied force, whereby an opposed area formed between the first conductor pattern and the second conductor pattern disposed with the dielectric interposed between the first conductor pattern and the second conductor pattern changes, to thereby form a capacitance corresponding to the externally applied force between the first conductor pattern and the second conductor pattern, wherein each of the first conductor pattern formed on the circumferential surface of the inside member and the second conductor pattern formed on the outer circumferential surface of the outside member so as to oppose the first conductor pattern formed on the circumferential surface of the inside member includes a plurality of conductor patterns, which are formed to extend in a direction that intersects the direction of the central axis and are arranged along the direction of the central axis, and the plurality of conductor patterns arranged along the direction of the central axis are coupled to each other by a connecting pattern. an inside member; and an outside member including a space for housing the inside member; the inside member having a columnar shape, and having a first conductor pattern formed on a circumferential surface of the inside member; the outside member being a dielectric having a predetermined dielectric constant, and having a second conductor pattern formed on an outer circumferential surface of the outside member, the second conductor pattern being disposed so as to oppose the first conductor pattern formed on the circumferential surface of the inside member when the inside member is housed in the space of the outside member; and the inside member housed in the space of the outside member and having the columnar shape being displaced relative to the outside member in a direction of a central axis of the inside member having the columnar shape in response to an externally applied force, whereby an opposed area formed between the first conductor pattern and the second conductor pattern disposed with the dielectric interposed between the first conductor pattern and the second conductor pattern changes, to thereby form a capacitance corresponding to the externally applied force between the first conductor pattern and the second conductor pattern, wherein each of the first conductor pattern formed on the circumferential surface of the inside member and the second conductor pattern formed on the outer circumferential surface of the outside member so as to oppose the first conductor pattern formed on the circumferential surface of the inside member includes a plurality of conductor patterns, which are formed to extend in a direction that intersects the direction of the central axis and are arranged along the direction of the central axis, and the plurality of conductor patterns arranged along the direction of the central axis are coupled to each other by a connecting pattern.
