Abstract

Provided is a moisture absorbing and releasing material including a polyether polyamide in which a diamine constituent unit thereof is derived from a specified polyether diamine compound (A-1) and a xylylenediamine (A-2), and a dicarboxylic acid constituent unit thereof is derived from an α,ω-linear aliphatic dicarboxylic acid having from 4 to 20 carbon atoms, wherein in the case where when held at 23° C. and 80% RH, its coefficient of saturated moisture absorption is defined as 100%, a normalized coefficient of moisture absorption after holding in an environment at 23° C. and 80% RH until a coefficient of moisture absorption reaches a saturated state and then further holding in an environment at 23° C. and 50% RH for 60 minutes is from 1 to 50%.
