Abstract: A glass electrode is capable of measuring a cation concentration of a test solution. The glass electrode includes a flat sensitive glass body sensitive to ions, a base body formed of a glass tube housing an internal solution, and a fixation layer used to sealingly attach the sensitive glass body to an end surface of the base body. A resistance value of the fixation layer is equal to or higher than a resistance value of the sensitive glass body. A liquid property measurement device is equipped with the glass electrode.

Abstract: An imaging apparatus includes a semiconductor light-emitting device functioning as a strobe light having a current limitation unit for limiting current to flow to the semiconductor light-emitting device. The current limitation unit limits current to flow to the semiconductor light-emitting device under a predetermined condition for increasing a current consumption amount.
