The present invention relates to a pressure sensor (1) which detects variation in pressures, the pressure sensor including a cantilever (4) which is bent according to a pressure difference between the inside and the outside of a cavity in a sensor main body, and an intra-lever gap (21) which is formed on a proximal end portion (4a) of the cantilever. The proximal end portion is partitioned into a first support portion (22) and a second support portion (23) by an intra-lever gap in a second direction (L2) orthogonal to a first direction (L1) in which the proximal end portion and a distal end portion (4b) are connected to each other in plan view. A doped layer (24) which is provided on a portion of the first and second support portions forms a first displacement detection portion (25) and a second displacement detection portion (26). Lengths of the first and second displacement detection portions are shorter than those of the first and second supports along the second direction.

The present invention provides a pressure sensor (1) which detects variation in pressure, the pressure sensor including a cantilever (4) which bends according to a pressure difference between the inside and the outside of a cavity in a sensor main body, and a first gap (21), a second gap (22), and a third gap (23) which are formed on a proximal end portion (4a) of the cantilever. The first to third gaps electrically partition the proximal end portion of the cantilever into a first support portion (24), a second support portion (25), a first displacement detection portion (26), and a second displacement portion (27) in a second direction (X2) orthogonal to a first direction (X1) in which the proximal end portion and a distal end portion (4b) of the cantilever are connected to each other in plan view. The first and second displacement detection portions detect displacement according to the bending of the cantilever between the first and second support portion.
