A forming method for a fiber aggregate in which fibers are heated to be welded with each other, the method includes a heating step of applying upward heated air to a bottom of a block of the fibers to pass the heated air therethrough and to cause the block of fibers to float, wherein at least parts of fibers are melted while the block of the fibers float; a compression step of compressing substantially in a vertical direction the heated block of fibers into a desired height; and a cooling step of cooling the compressed block of fibers to solidify melted portions of the fibers at portions where the fibers intersect with each other.
