The present invention provides an adhesive kit offering both excellent adhesion to the teeth and excellent latitude of time for manipulation after contact between the pre-treatment material and adhesive material. The present invention is an adhesive kit comprising: a pre-treatment material (A) containing an acidic group-containing radical polymerizable monomer (a1), a vanadium compound (a2), a solvent (a3), and a hydrophilic radical polymerizable monomer (a4) having no acidic group; and an adhesive material (B) containing a radical polymerizable monomer (b1) having no acidic group, a C5 or higher hydroperoxide compound (b2) having at least one hydroperoxide group bonded to a tertiary carbon, pyridylthio urea or a derivative thereof (b3), and a filler (b4) as requisite components, and also containing 0-3 parts by weight of an acidic compound (b5) relative to 100 parts by weight total of (b1), (b2), and (b3).
