    • PROBLEM TO BE SOLVED: To provide protective equipment for a particulate matter detection device, which prevents the particulate matter detection device from being cooled by the flow of an exhaust gas and which prevents the particulate matter detection device from being broken down by water mixed with the exhaust gas or the like, when the particulate matter detection device is attached to a pipe of the exhaust gas or the like. SOLUTION: The protective equipment 100 for the particulate matter detection device includes a bottomed cylindrical protective equipment body 4 having a cylindrical trunk portion 1 and a bottom portion 3 which closes one end 2 of the trunk portion 1, and there are formed a gas introduction port 5 which extends through a wall of the trunk portion 1 and through which the gas flows from the outside to the inside and a gas discharge port 6 which extends through a wall of the trunk portion 1 at a position facing the gas introduction port 5 and through which the gas is discharged from the inside to the outside.
