PROBLEM TO BE SOLVED: To seal terminal parts for supplying power to the motor of a canned motor pump securely. SOLUTION: A terminal block 38 has a linkage path through which the inside and outside of a stator enclosing vessel 34 are communicated. Terminals 46 are provided on the tip of the terminal block 38 so as to close the linkage path. The terminals 46 are pressed against the tip of the terminal block 38 by a terminal holder 60 with an O-ring 68 therebetween. The tight sealing between the circumferences of the terminals 46 and the terminal block 68 is secured by the O-ring 68. Three terminal wires 52 penetrate the sealing parts 48 and 50 of the terminals 46 which close the linkage path. Each terminal wire 52 is composed of one solid metal wire and does not have interstices between strands of a stranded wire. Therefore, the tight sealing between the inside and outside of the stator enclosing vessel 34 is not deteriorated by the terminal wires 52.
