PROBLEM TO BE SOLVED: To enable to easily adjust density and to improve the touch of a capsule particle at the time of breaking by incorporating a gas in an inner layer to lessen the lowering of the strength of the capsule particle with respect to the seamless capsule particle composed of the inner layer and a coating film formed by coating the inner layer. SOLUTION: Relating to the seamless capsule particle, which is a capsule particle used for drugs, foods and the like and constituted of the inner layer and the coating film formed by coating the inner layer, the gas is incorporated in the inner layer so as to occupy 1-100 vol.% of the inner layer. The inner layer is formed from one containing one or more kinds of structural components selected from a water soluble component, an oily component and a surfactant component and as the gas, one or more kinds selected from nitrogen, argon and helium is used. And the ratio of the coating film volume to the volume of the capsule particle is controlled to 15-80 vol.%. Further, the capsule particle is formed to be 0.5-500 gf/piece in the strength of the capsule particle and 0.100-1,300 g/cm<3> in the density of the capsule particle. |
