<p>The purpose of the present invention is to provide: an adhesive agent composition which can exhibit excellent adhesiveness when used in the form of an adhesive sheet, and which can prevent the occurrence of improper operating under a wide temperature environment ranging from a low temperature to a high temperature when used in the form of an adhesive sheet in a capacitive touch panel; an adhesive sheet produced from the composition; a laminate for a touch panel, which is equipped with the adhesive sheet; and a capacitive touch panel sensor. The adhesive agent composition according to the present invention comprises a monoacylphosphine oxide (A1), a bisacylphosphine oxide (A2) and a radically polymerizable monomer (B) having a specific group and having a specified solubility parameter, wherein the content of the component (A1) relative to the whole amount of the composition is 1.5% by mass or more, the ratio (b/a) of the content (b) of the component (B) to the total content (a) of the components (A1) and (A2) is 3.0 to 30.0 by mass, and the ratio of the number of moles of oxygen atoms contained in the composition to the number of moles of carbon atoms contained in the composition is 0.1 or less.</p> |
