A crosslinked polyolefin resin foam sheet according to the present invention has an amine compound concentration of 0.006-0.04 ppm by volume in a nitrogen gas containing an amine compound obtained by filling 5 L of nitrogen gas into a 10 L sampling bag in which two crosslinked polyolefin resin foam sheets having a size of 100 mm * 100 mm * 3.0 +/-0.2 mm are placed, and then filling the nitrogen gas into the sampling bag. And heating the sampling bag at a heating temperature of 80 DEG C for 2 hours. A molded article according to the present invention is obtained by molding the crosslinked polyolefin resin foam sheet according to the present invention. According to the present invention, it is possible to provide: a crosslinked polyolefin resin foam sheet in which contamination of an extruder can be suppressed and odor generation can be reduced when a crosslinked polyolefin resin foam sheet is produced using the extruder; and a molded article obtained by molding the crosslinked polyolefin resin foam sheet. 本发明的
