<P>PROBLEM TO BE SOLVED: To provide an air bubble detecting device using an inexpensive detection capacitor. <P>SOLUTION: The detection capacitor used in the air bubble detecting device is a coiled capacitor body 10 comprising: a tubular body 1 made of electric insulating resin having a flange-like terminal block 1a in the center; a first coiled electrode 2 and a second coiled electrode 4 that are mutually independent and wound respectively on both sides of the flange-like terminal block 1a in the lengthwise direction of the tubular body 1; and a first terminal pin P<SB POS="POST">1</SB>and a second terminal pin P<SB POS="POST">2</SB>embedded in the flange-like terminal block 1a. One end of a first winding line W<SB POS="POST">1</SB>constituting the first coiled electrode 2 is connected to the first terminal pin P<SB POS="POST">1</SB>, and the other end of the first winding W<SB POS="POST">1</SB>is an open end hooked to a first slit S<SB POS="POST">1</SB>formed at a first coil end flange section F<SB POS="POST">1</SB>. Also, one end of a second winding W<SB POS="POST">2</SB>constituting the second coiled electrode 4 is connected to the second terminal pin P<SB POS="POST">2</SB>and the other end of the second winding W<SB POS="POST">2</SB>is an open end hooked to a second slit S<SB POS="POST">2</SB>formed at a second coil end flange section F<SB POS="POST">2</SB>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
