To provide a glass ionomer cement having excellent removality of the surplus cement after curing because of having shape retaining property where a kneaded material does not drip and flow by their own weights, few risk of water sensitivity and excellent operability at the bonding such that surplus cement can be removed easily after an application in an oral cavity in an early timing in spite of exhibiting a thin coating thickness at the bonding. A glass ionomer cement composition for dental luting comprises at least； a component (a) acid reactive glass powder having an average particle diameter within a range of 4.5 to 7.0 µm, a component (b) polymer of an acid group-containing polymerizable monomer having a weight average molecular weight within a range of 30000 to 100000,a component (c) chelating agent and a component (d) water, wherein a plastic flow distance of a kneaded material before curing is 2 mm or less, and a removal possible time of a surplus cement is 2 minutes or less.
