The disclosure relates to a multiple pane which includes a pair of glass panels spaced by the spacers and sealed at peripheries thereof. The objective is to provide a multiple pane in which the spacers are formed easily, and a method of preparing the multiple pane. The multiple pane includes: a pair of glass panels; a plurality of spacers interposed between the pair of glass panels; and a hermetic bond to hermetically bond peripheries of the pair of glass panels to each other. The multiple pane contains a space formed between the pair of glass panels, the space being to be sealed so as to be in a reduced pressure state. Each of the plurality of spacers being a porous member formed on one glass panel of the pair of glass panels.
