Abstract: A polypropylene multilayer sheet includes:



a biaxially oriented polypropylene layer F having a melting point TmF; and
a biaxially oriented polypropylene layer N having a melting point TmN,
the biaxially oriented polypropylene layer N and the biaxially oriented polypropylene layer F being alternately laminated,
the polypropylene multilayer sheet having a thickness of 0.15 mm to 3.0 mm, wherein:

TmF>TmN,

a total number of layers is 3 to 11,
the biaxially oriented polypropylene layer F is formed of a resin composition containing: a polypropylene-based resin as a component (A); and an inorganic filler as a component (B),
a weight ratio of the component (B)/[the component (A)+the component (B)] is 0.5 to 60 wt %,
the biaxially oriented polypropylene layer N is formed of a resin composition containing: a polypropylene-based resin as a component (a); and the component (B) as an optional component, and
a weight ratio of the component (B)/[the component (a)+the component (B)] is 0 to 10 wt %.
