A hydrogen generation apparatus (1) is configured to be supplied with a raw material containing a hydrocarbon component and generate a hydrogen-containing fuel gas. The hydrogen generation apparatus (1) includes: a reformer (10) configured to cause a reforming reaction of a mixed gas of the raw material and steam; a combustor (2) configured to combust a combustible gas to heat the reformer (10); a hydrodesulfurizer (14) configured to be supplied with heat from the reformer (10), and cause a reaction between sulfur in the raw material that is to be supplied to the reformer (10) and hydrogen to remove the sulfur from the raw material; a first heat insulating material (13) disposed between the hydrodesulfurizer (14) and the reformer (10); and a heat equalizing plate (18) disposed between the hydrodesulfurizer (14) and the first heat insulating material (13).
