PURPOSE:To obtain the title product suitable as an ion sensor, capable of readily determining ion concentration by simply dripping a minimal amount of a sample solution by providing, along the longer direction of one side of a tape, such an ion-selective membrane as to change the absorbance for a specific waveband depending on ion concentration. CONSTITUTION:The objective product can be obtained by providing, along the longer direction of one side of a tape, such an ion-selective membrane 52 as to change the absorbance for a specific wavelength or specific waveband depending on ion concentration. It is preferable that a recess 53 capable of holding the droplets of a sample solution at a proper site and of preventing the overflow of said droplets be prepared. Said ion-selective membrane is e.g. a polyaniline membrane. |
