Abstract
This steering wheel includes a ring portion to be gripped during steering, a core having at least one ridge, and a core coating layer coating the core. The core coating layer has a relatively hard portion formed of a first synthetic resin and a relatively soft portion formed of a second synthetic resin arranged in the circumferential direction relative to each other. The relatively hard portion is harder than the relatively soft portion. The ridge is positioned along the core so as to be covered by the relatively hard portion.
