The present invention provides a metering type mat including a breathable bottom layer, a water-absorbing layer, a leak-proof layer, and a flexible surface layer. The water-absorbing layer is disposed on the air-permeable bottom layer. The leak-proof layer is disposed between the air-permeable bottom layer and the water-absorbing layer, and surrounds a peripheral edge of the water-absorbing layer. The flexible surface layer covers the water-absorbing layer, the leak-proof layer and the air-permeable bottom layer, and an outer surface facing away from the water-absorbing layer is provided with a plurality of first lines spaced from each other, and a plurality of lines spaced from each other and spaced from the first A second line interlaced with each other, and the first line and the second line together define a grid structure.本新型提供一種計量型產褥墊，其包括一透氣性底層、一吸水層、一防漏層，及一柔性表層。該吸水層設置於該透氣性底層上。該防漏層設置於該透氣性底層與該吸水層間，並包圍該吸水層的一周緣。該柔性表層覆蓋該吸水層、該防漏層與該透氣性底層，並於背向該吸水層的一外表面設置有複數彼此間隔排列的第一線條，及複數彼此間隔排列並與該等第一線條彼此交錯的第二線條，且該等第一線條與該等第二線條共同定義出一網格結構。
