Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a temperature-sensitive adhesive tape and a temperature-sensitive adhesive sheet excellent in fixability and peelability.SOLUTION: A temperature-sensitive adhesive tape has a base material and an adhesive layer laminated on one surface or both surfaces of the base material, where the adhesive layer is formed of a cured product of a temperature-sensitive adhesive composition. A temperature-sensitive adhesive sheet is formed of a cured product of the temperature-sensitive adhesive composition. The temperature-sensitive adhesive composition contains 5 pts.wt. or less of polyfunctional (meth)acrylate with respect to 100 pts.wt. of the total of a side chain crystalline (meth)acrylic polymer, a (meth)acrylic monomer and a photoradical initiator.SELECTED DRAWING: None 【課題】固定性および剥離性に優れる感温性粘着テープおよび感温性粘着シートを提供することである。【解決手段】基材と、前記基材の片面または両面に積層されている粘着剤層と、を備え、前記粘着剤層が、感温性粘着剤組成物の硬化物からなる感温性粘着テープである。また、前記感温性粘着剤組成物の硬化物からなる感温性粘着シートである。前記感温性粘着剤組成物は、側鎖結晶性（メタ）アクリルポリマー、（メタ）アクリルモノマーおよび光ラジカル開始剤の合計１００重量部に対して、多官能（メタ）アクリレートを５重量部以下の割合で含有する。【選択図】なし
