PROBLEM TO BE SOLVED: To provide a method of manufacturing a compressed wood product, capable of creating a wood grain pattern excellent in design property with a naturally and continuously changed grain. SOLUTION: The method includes a blank piece forming step of forming a blank piece, the blank piece having a shape in which a circularly closed marginal part makes a first plane, only one space of two spaces divided by the first plane has an undulation that includes a plurality of convex vertices, a vertex of which height from the first plane is higher is located at a position closer to a geometrical center of the circularly closed marginal part among optional two vertices of the plurality of convex vertices when being viewed on a second plane that passes the two vertices and is perpendicular to the first plane, the blank piece having a volume obtained by adding an amount by which a volume of the blank piece is decreased by compression; a softening step of softening the blank piece formed in the blank piece forming step; and a compression step of compressing the softened blank piece in a water-vapor atmosphere having temperature and pressure higher than those of atmospheric air to deform the blank piece into a shape substantially like a bowl.
