A honeycomb core includes carbon fiber having four or more different fiber directions, and when a ribbon direction is set as an X axis direction, a cell width direction is set as a Y axis direction, and a direction that is orthogonal to the ribbon direction and the cell width direction is set as a Z axis direction. A condition in which angles formed by the X axis direction and the respective fiber directions of the carbon fiber are set at &#x2212;45 degrees, 0 degrees, 45 degrees, and 90 degrees is set as a reference condition. The respective fiber directions are rotated from the reference condition by a fixed rotation angle so that none of the fiber directions are parallel to the X axis direction.
