PROBLEM TO BE SOLVED: To provide a visible light-curable type repeelable pressure-sensitive adhesive composition capable of peeling off easily and without having leftover paste since exhibiting sufficient adhesive force before the irradiation of the visible light and decreasing the adhesive force sufficiently after the irradiation of the visible light. SOLUTION: This visible light-curable type repeelable pressure-sensitive adhesive is provided by containing (A component) a monomer having≥3 polymerizable carbon-carbon double bonds, (B component) an oligomer having≥2 polymerizable carbon-carbon double bonds, (C component) a polymer having 100,000 to 2,000,000 weight-average molecular weight and -60 to +45°C glass transition temperature and (D component) a photopolymerization initiator having a maximum absorption wavelength (λmax) at the wavelength region of≥400 nm by 5 to 70 mass% A component, 5 to 70 mass% B component and 10 to 80 mass% C component (provided that A component + B component + C component =100 mass%).
