A guidewire 1 includes a wire body 10 that has a first wire 2 which is arranged on a distal end side and a second wire 3 which is arranged on a proximal end side of the first wire 2 and is formed of a material whose rigidity is higher than that of a constituting material of the first wire 2, and in which a proximal end surface 241 of the first wire 2 and a distal end surface 311 of the second wire 3 are joined to each other so as to form a joint portion 14, an outer member 5 that is arranged on an outer peripheral side of the wire body 10, that forms a tubular shape which covers the wire body 10 at least from a distal end portion of the first wire 2 to the joint portion 14, and that has flexibility, and an inner member 4A that is arranged between an outer peripheral portion of the wire body 10 and an inner peripheral portion of the outer member 5, and that covers the joint portion 14. The inner member 4A is an inner coil formed by winding a wire for the inner member 41 into a coil shape.
