Zusammenfassung:	PROBLEM TO BE SOLVED: To propose an improvement in a shield body on a front side so that an optimal measurement characteristic can be maintained even with a thermal load asymmetrically acting on a sensor and even in a dynamic process of a strong level, and so that the measurement characteristic can be made appropriate.SOLUTION: The present invention relates to a pressure sensor (1) that comprises: a sensor housing (2) accommodating a measurement transducer (3); and a diaphragm (10) having a central pressure part (11) surrounded by an annular flexible part (12), and being arranged on a pressure side where to the pressure part (11), a shield body is attached which exerts an influence on a heat transfer. The shield body is formed as a distribution cap (20) that has a central area (24) bonded to the pressure part (11) by a heat transfer bonding. For example, a central recess part or an opening part (23) is formed and a protrusion part (16) of the pressure part (11) can be accommodated.
