The invention relates to a needle type roughmeter, which comprises a support frame, a motion part, a plurality of faceplates and steel needles, wherein the support frame is provided with parallel slide rails; the motion part is positioned in the support frame and slides along the parallel slide rails, and the relative inner side wall of the motion part is provided with a plurality of faceplate inserting grooves; the faceplates are inserted into the faceplates inserting grooves and are provided with a plurality of vertical steel needles inserting grooves along the length direction; and the steel needles are inserted into the steel needles inserting grooves and can vertically fall onto the ground along the steel needles inserting grooves. The needle type roughmeter measures the roughness ofthe fixed surface, can measure area arrays for once and measure surfaces with a certain gradient, is convenient in operation, and has high precision.
