Claim Text:
1. A sample cartridge for measuring the electrical characteristics of a liquid sample, the sample cartridge being made by forming an insulating material into a tubular body having a first end and a second end, wherein the sample cartridge is configured to hold the liquid sample in a region that is defined by: (1) outer surfaces of two electrodes that face each other and are respectively inserted within an inner cavity of the tubular body between the first and second ends and (2) a first surface and a second surface of the inner cavity that face each other, and wherein a narrowing portion comprising a narrowed inner cavity is provided between the outer surfaces of the two electrodes, wherein the narrowing portion is formed by (1) a first partition wall that protrudes to the inner cavity side from at least a first portion of the first surface of the inner cavity of the tubular body and (2) a second partition wall that protrudes to the inner cavity side from at least a second portion of the second surface of the inner cavity of the tubular body, wherein the first partition wall and the second partition wall are formed opposite to each other and face each other, wherein the first surface of the inner cavity and the second surface of the inner cavity are formed between the outer surfaces of the two electrodes facing each other.
