To obtain a refrigerant compressor having a sealing terminal that can prevent the fall-out of a pin and suppress rapid refrigerant blowout when an insulation fixing part is broken.
A sealing terminal 60 includes: a metal body 61 that is fixed to a sealing terminal connection hole 40b provided on a wall surface of a sealing container 40; a conductive pin 62 that is insulated and fixed to a through-hole 61a of the body 61 while one end side of the conductive pin protrudes to the inside of the sealing container 40 and the other end side of the conductive pin protrudes to the outside of the sealing container 40; a glass seal 63 that fixes the through-hole 61a of the body 61 and the pin 62 so that they are insulated; a fall-out prevention part 64 that is provided on one end of the pin 62 for preventing the pin 62 from falling out from the sealing container 40 when the gas seal 63 is broken; and a refrigerant path 65 that forms a communication path connecting the inside and outside of the sealing container 40 along with the through-hole 61a while the glass seal 63 is broken, the fall-out prevention part 64 of the pin 62 contacts an opening end surface 61b of the through-hole 61a by an internal pressure in the sealing container 40 and the fall-out of the pin is prevented.
