Provided are a spiral type membrane element that can re-collect the electric power that is used in a good manner, and a spiral type membrane filtering device having the same. The spiral type membrane element comprises a power generating section that generates electric power by using a liquid, and an electric power outputting section that outputs, either in a wired manner or in a wireless manner, the electric power supplied from said power generating section. The electric power that is generated in the power generating section using the liquid (raw water, permeated water, or concentrated water) can be output from the electric power outputting section in a wired manner or in a wireless manner. Therefore, the electric power that is output from the aforesaid electric power outputting section can be used in an electric component disposed outside or can be stored into a capacitor section disposed outside.

The purpose is to provide an immunity-inducing agent which can be implanted or injected in vivo by a simple operation and is capable of activating the in vivo immunological actions without causing adverse side effects. An immunity-inducing agent comprising β-tricalcium phosphate (β-TCP) having a porosity of 50% or less is implanted or injected in vivo, particularly in the vicinity of a lesion area (non-lesion area) such as cancer. Lymphocytes such as T cells, B cells and NK cells or a dendritic cell can be induced in the vicinity of β-TCP, and a lymphadenoid tissue is formed in which lymphocytes are localized at a high density. Examples of the dosage form of the immunity-inducing agent include particles or granules having a particle or grain size of equal to or greater than 0.05 μm and less than 25 μm, as well as tablets or columellas.
