摘要：
A thin biaxially oriented film excellent in dimensional stability against humidity change, as well as a magnetic recording medium and a film capacitor using the same. The present invention provides a laminated biaxially oriented film comprising: at least one layer comprising an aromatic polyester (a); and at least one layer of a polyolefin (b) having a melting point of from 230 to 280° C.; wherein the ratio of the polyolefin (b) is from 2 to 60% based on the entire weight of the film, and the film thickness is from 1 to 10 μm.
