Abstract
Magnetic sensorhas magnetic field detection elementthat detects a magnetic field that is generated by magnetthat rotates about central axis C; and substratethat has first side Pand second side Pthat is a reverse side of the first side P, wherein second side Pincludes first slope PKthat is inclined with respect to first side P. Magnetic field detection elementis provided along first slope PK. Magnetis separated from central axis C and polarities of magnetalternate in a circumferential direction about central axis C. First side Pis substantially parallel to central axis C. First slope PKis inclined with respect to first side Pby an average angle of. In a plane perpendicular to central axis C, intensity of the magnetic field where magnetic field detection elementis positioned changes as magnetrotates, and the relation(1/)×0.8≤≤(1/)×1.2(=sin θ)
