To provide a liquid guiding device such that, when liquid is dumped onto a sloping guiding surface portion located in a region where ink is dumped, the liquid is easily guided to an ink absorber and no liquid remains on the guiding surface portion. A guiding surface portion 29 is provided in a liquid dumping region 23 in which ink absorbers 25 and 26 are provided and on the upstream edge of a downstream portion 24 of a platen. The upper surface of the guiding surface portions 29 slopes down toward the upstream side, that is, toward the liquid dumping region 23. In the guiding surface portion 29 is formed a guiding structure portion 31 that guides ink attached to the guiding surface portion to the ink absorber 25. The guiding structure portion may include an edge portion 31 that guides liquid by capillary action. The edge portion may extend to the ink absorbers 25 and 26.
