PROBLEM TO BE SOLVED: To provide a PCL (polycaprolactone)-foamed material having a uniform bubble diameter and a method for producing the same. SOLUTION: This method for producing the polyε-caprolactone-foamed material is provided by dispersing an alkali metal chloride in the polyε-caprolactone, then dissolving a fluid under a super critical state into the polyε-caprolactone under pressure, and then releasing the pressure rapidly for forming bubbles in the polyε-caprolactone.
