Temperature sensor and thermal flow-measuring device

A temperature sensor, of a thermal flow-measuring device, comprising:

• a housing, which comprises a housing body from which at least a first shell and a second shell protrude, each of which shells comprises a first end section, a second end section and a longitudinal axis, said longitudinal axis extends between said first and said second end sections;
• a temperature sensor element arranged in the region of said first end section, which has especially a thin-film resistance thermometer;
• and
• from each temperature sensor element at least one connection wire leads away, which is connected with a circuit board, wherein:
• one of said temperature sensor elements is heatable, and which shells have outsides, which interface the housing with the environment;
• said housing body has a housing chamber, which is connected with inner hollow spaces of said shells;
• and
• said circuit board is arranged in said housing chamber, and is positioned in said housing chamber by a snap-in connection.
