PROBLEM TO BE SOLVED: To provide a styrenic resin composition suitable for production of plate-like extruded foam excellent in extrusion foamability and mechanical strength during production of plate-like extruded foam especially using a hydrocarbon-based foaming agent, and a method for producing it. SOLUTION: Using a styrenic resin composition having a particular range of fluidity (melt mass flow rate) and a melt-tension value, as well as a particular range of weight-average molecular weight (Mw), molecular weight distribution (Mw/Mn, Mz/Mw) enables production of plate-like foam excellent in mechanical strength.
