A catalytic converter comprises: a catalyst carrier (12) that purifies exhaust gases from an internal combustion engine; and a catalyst housing tube (11) that houses the catalyst carrier (12). The catalyst housing tube (11) comprises: an inlet-side conical part (11c) that comprises an exhaust-gas inlet (11a), an inner diameter of the inlet-side conical part (11c) increasing as a distance from the exhaust-gas inlet (11a) increases; a tube part (11d) that comprises the catalyst carrier (12) arranged therein; and, an outlet-side conical part (11e) that comprises an exhaust-gas outlet (11b), an inner diameter of the outlet-side conical part (11e) increasing as a distance from the exhaust-gas outlet (11b) increases. A conical inner tube (14) is further provided inside the inlet-side conical part (11c), a diameter of the conical inner tube (14) being smaller than that of the inlet-side conical part (11c), and, the inlet-side conical part (11c) and the conical inner tube (14) form a double structure upstream of the catalyst carrier (12).
