Abstract
A heating device includes a magnetic field heating coil that inductively heats a composite material by a magnetic field. The composite material has a length in a depth direction and a length in a width direction orthogonal to the depth direction. The magnetic field heating coil has a first coil part provided along the width direction, and a pair of second coil parts provided on both sides of the first coil part in the width direction so as to be continuous with the first coil part, the second coil parts being tilted a predetermined angle θ to one side in the depth direction with respect to the width direction. The first coil part and the second coil parts are symmetric with respect to a line segment drawn in the depth direction at a center of the first coil part in the width direction.
