The present invention provides a chrome-plated sliding member free from periodical decreases in wear resistance or seizure resistance without the necessity to intentionally bend a multi-layer hard chrome plating film. This is a sliding member having a multi-layer hard chrome plating film on the sliding surface of the substrate 1. Microcracks 6 opening to the outer surface side of the individual hard chrome plating layers are distributed in hard chrome plating layers 2, 3, 4 and 5. The microcracks of the individual hard chrome plating layers comprise relatively shallow portions 6a where bottoms stop within a single layer, and relatively deep portions 6b and 6c where cracks run through two or more layers. The quantities of the microcracks expressed by the area ratios of microcracks on a cross-section of the hard chrome plating film include a quantity of the portions where cracks stop within a single layer within a range of from 1.5 to 35.0%, a quantity of the portions where cracks run through two or more layers within a range of from 0.5 to 25.0%, and a total quantity of microcracks within a range of from 2.0 to 40.0%.
