A semiconductor pressure sensor and method for its manufacture. Preferably, the pressure sensor is used as an absolute pressure sensor. The pressure sensor includes a pressure sensor chip of semiconductor material, the pressure sensor chip including a piezoresistive diaphragm. The pressure sensor is arranged in a casing which has an aperture for transmitting the ambient pressure to the diaphragm of the pressure sensor chip. The pressure sensor chip is fastened on a conductive tape and the conductive tape is a component of the casing. The casing consists of a hard synthetic material and contains the pressure sensor chip. The casing is configured so that the method of manufacture and tooling for manufacture allow cost-efficient production. The casing also offers protection for the pressure sensor during testing, equipping and during application in a circuit. The pressure sensor also includes a soft elastic material for covering the pressure sensor chip and transmitting ambient pressure from the aperature to the diaphragm.
