A vehicle position calculating apparatus has relative position calculating means for calculating a relative vehicle position with respect to a reference position and absolute position calculating means for calculating an absolute vehicle position from fixed-station absolute position information and vehicle bearing information which are obtained from a radio wave transmitted from a fixed station and the above-described relative vehicle position. The relative position calculating means includes means for calculating a present vehicle position by employing absolute positions successively obtained as new reference positions. Accordingly, it is possible to accurately obtain an absolute present vehicle position.

Metallized layers are formed respectively on the surfaces to be joined of the ceramic members by performing metallized treatment on the surfaces, and then, these metallized layers are pressed against each other, and under pressure are diffusion-bonded at high temperature. A metal foil which can form a solid solution with the metallized layers can be interposed between the metallized layers before diffusion-bonding. This method can be used to manufacture an oxygen sensor element.
