Provided is a polyolefin base porous film comprising a polyolefin composition in which calcium carbonate particles, preferably calcium carbonate particles subjected to surface treatment with chain carboxylic acid having 3 to 6 carbon atoms are dispersed. This polyolefin base porous film is characterized by that the leached solution with water has a pH which falls in the vicinity of neutrality and has a low stimulation to the skin, and therefore it is useful for goods contacting human bodies, particularly a back sheet for a sanitary napkin.
