There is disclosed a solid semiconductor element which very efficiently detects information about a liquid and bidirectionally exchanges the information with the outside. The solid semiconductor element is disposed in a liquid container, and includes at least energy converting unit, information acquiring unit, and information communicating unit. The energy converting unit converts an electromotive force from the outside to a power, and operates the information acquiring unit and information communicating unit. The information acquiring unit acquires the information about the liquid in which the solid semiconductor element is disposed from the liquid, and the information communicating unit transmits the information acquired by the information acquiring unit to the outside.

Solid semiconductor element, ink tank, ink jet recording apparatus provided with ink tank, liquid information acquiring method and liquid physical property change discriminating method

A solid type semiconductor device comprises energy converting means for converting energy from outside, and operating means operated by energy converted by the energy converting means. The energy converting means converts the electromotive force supplied from the outside to the device in non-contact into electric power. The operating means comprises information acquiring means actuated by electric power obtained by energy converting means; discriminating means; information accumulating means; and information communicating means.
